Abstract
The U.S. Department of Homeland Security (DHS), U.S. Customs and Border Protection
(CBP), launched a new public-facing mobile application, CBP One™, to provide the public a
single portal to a variety of CBP services. CBP One™ will eventually replace and upgrade existing
CBP public-facing mobile applications to improve user interaction and services. CBP One™
includes different functionality for travelers, importers, brokers, carriers, and International
Organizations under a single consolidated log-in and uses guided questions to help users determine
the correct services, forms, or applications needed. CBP is conducting this Privacy Impact
Assessment (PIA) to address privacy risks in the deployment and use of the CBP One™ mobile
application.

Introduction
On October 28, 2020, CBP launched the CBP One™ mobile application. CBP One™ is a
mobile application that serves as a single portal to a variety of CBP services. Through a series of
guided questions, the application will direct each type of user to the appropriate services based on
their needs.
CBP One™ is available for Android and iOS mobile
devices in the Google Play or iTunes mobile application stores.
Users have to create a new or open an existing Login.Gov1
account in order to access CBP One™. Login.Gov ensures a
secure connection and identity verification for CBP One™
users. In order to register with Login.gov, users have to provide
an email address and a phone number and create a password.
Login.gov does not share any information provided by the user
with CBP. Each time a user launches CBP One™, a
notification displaying the CBP Privacy Policy will appear and
users must consent to it prior to using the mobile application.
Once the user has logged in via Login.gov and
consented to the privacy policy, the landing page will launch
which permits the user to select from different options that
describe the individual’s reason for using CBP One™. CBP
One™ will display different functions based on the user’s
selections. For some functions, users are able to input

information for themselves, as well as for others. This makes it easier for groups to submit
information, and streamlines CBP’s vetting and inspection processes.
Currently, CBP One™ is available for brokers/carriers/forwarders to make appointments
for the inspection of perishable cargo and travelers to apply for and view their I-94s. In addition,
CBP One™ is available to International Organizations,2 authorized by persons asserting
enrollment in the Migrant Protection Protocols (MPP)3 Program, to submit biometric and
biographic information to verify enrollment in MPP on their behalf. Eventually, aircraft operators,
bus operators, seaplane pilots, commercial truck drivers, vessel operators, or agents will be able to
use CBP One™. CBP will add appendices to this PIA to describe new functions as they are
launched in the application. Depending on the function, CBP may also publish standalone,
function-specific PIAs to fully analyze the risks and mitigations CBP has put in place to protect
individual privacy.
Travelers
Individuals traveling into or exiting the United States will be able to use CBP One™ to
inform CBP of their arrival and departure consistent with applicable laws. Additionally, travelers
will be able to use CBP One™ to apply for certain CBP benefits, such as membership into CBP’s
Trusted Traveler Program, as well as view some information CBP may maintain on the traveler.
At launch, the I-94 functionality in CBP One™ mirrored the I-94 website functionality.4
This allows nonimmigrant aliens to apply for a provisional I-94, pay in advance of arrival for an
I-94, retrieve their most recent I-94, view their travel history, and check their authorized period of
stay on any active I-94. By Spring 2021, CBP will pilot a new Self-Reporting Mobile Exit feature.
This new feature will allow some nonimmigrant aliens to self-report their exit from the United
States at certain ports of entry on the Northern Border. Appendix A of this PIA describes the I-94
functionality of CBP One™ and CBP will publish a standalone, function-specific PIA before
making the Self-Reporting Mobile Exit feature active.

An International Organization is an organization that established a treaty or other instrument governed by
international law and possessing its own international legal personality, such as the United Nations (UN), the World
Health Organization (WHO), and North Atlantic Treaty Organization (NATO). For the purpose of this PIA,
International Organizations have established roles supporting the Government of Mexico to provide services to
undocumented individuals under the Migrant Protections Protocol (MPP).
3
The MPP are a U.S. Government action whereby certain foreign individuals entering or seeking admission to the
United States from Mexico – illegally or without proper documentation – may be returned to Mexico and wait
outside of the United States for the duration of their immigration proceedings, where Mexico will provide them with
all appropriate humanitarian protections for the duration of their stay. Additional information is available at
https://www.dhs.gov/news/2019/01/24/migrant-protection-protocols. Appendix C of this PIA further outlines the
implementation of MPP through CBP One™.

Also by Spring 2021, CBP plans on moving the standalone CBP ROAM™ mobile
application under the CBP One™ umbrella. CBP ROAM™ permits small pleasure boat operators
along the Northern Border to report their arrival into United States. In the future, CBP ROAM™
will be removed from the Google Play and iOS mobile application stores, and travelers will have
to use CBP One™ to complete the same transactions. CBP will update Appendix A of this PIA
and publish a standalone, function-specific PIA once this offshore arrival reporting functionality
is available in CBP One™.
Broker/Carrier/Forwarder Agents
The Inspection Appointment request feature allows brokers/carriers/forwarders to schedule
and check the appointment status of an inspection of commercial vessels or for cargo entering the
United States. CBP One™ streamlines the scheduling process, which previously required multiple
phone calls and exchange of information between brokers/carriers/forwarders and CBP officers or
agriculture specialists. Using CBP One™, brokers/carriers/forwarders create a profile that includes
contact and port of entry information. Users then request a specific day and time for inspection of
their vessel or goods by a CBP officer or agriculture specialist. CBP officers or agriculture
specialists use a dashboard outside of CBP One™ to view the requests and assign inspection times.
The CBP officer or agriculture specialist can also use the dashboard to communicate with the
broker/carrier/forwarder, using CBP One™, in order to gain any additional information. Finally,
brokers/carriers/forwarders are able to cancel and reschedule an inspection request through CBP
One™. CBP One™ inspections of cargo can also be accessed via a desktop application. In the
future, CBP plans to incorporate all cargo into the desktop application.
Operators
Operators are representatives of a company, such as bus drivers and plane pilots, who are
authorized to use CBP One™ to submit manifest information to CBP. Sea, land, and air operators
will be able to use CBP One™ to submit information to CBP on behalf of consenting travelers
through applications, such as the I-94 mobile application. Operators will use the application to
gather information from travelers in order to bulk submit information to CBP. Operator capabilities
will not be available in CBP One™ at launch. Once operator functionality launches, CBP will
create an appendix to this PIA and, as necessary, publish a standalone PIA Update documenting
the new features.
International Organizations
CBP has formed partnerships with International Organizations to assist aliens seeking
admission into the United States. Access to the International Organization functionality within
CBP One™ is limited to International Organizations identified by the United States Department
of State (DoS) as having established roles supporting the Government of Mexico to provide
services to MPP enrollees. If the user is not a verified International Organization, the individual

Privacy Impact Assessment Update
CBP/PIA-068 CBP One™ Mobile Application
Page 4

will not see the International Organization persona in the list of options on the CBP One™
homepage. Appendix C of this PIA provides additional guidance on the use and functionality of
the International Organization feature and CBP is developing a standalone, function-specific PIA
for the MPP program.
Information Collected
The information users provide to CBP depends on the function of CBP One™ that they are
using. Individuals using CBP One™ to report their travel into and out of the United States have to
provide more information than users scheduling agriculture inspection appointments. Users will
have to provide basic biographic information, such as first and last name, contact information, and
email address, in order to create a Login.gov account and use the application. Regardless of the
function, CBP One™ does not store any information locally on the device. CBP pushes all
information collected through CBP One™ to back-end systems associated with the functions the
user is using. For example, CBP will store information related to I-94 information submitted
through CBP One™ in CBP’s I-94 databases.
Compliance Framework
In its initial phase, CBP One™ is operational for users to schedule an agricultural
inspection or apply for an I-94 prior to arrival. CBP One™ will continue to expand to become the
unified mobile portal for public transactions with CBP. CBP is conducting this overarching PIA
to describe the risks and mitigations associated with CBP One™; however, due to broad and
disparate functions contemplated for CBP One™, CBP will conduct standalone, function-specific
PIAs for each function as necessary. CBP will add or update the Appendices to this PIA as new
functions are developed to ensure transparency regarding all publicly available CBP mobile
applications.

Fair Information Practice Principles (FIPPs)
The Privacy Act of 19745 articulates concepts of how the federal government should treat
individuals and their information and imposes duties upon federal agencies regarding the
collection, use, dissemination, and maintenance of personally identifiable information. The
Homeland Security Act of 2002 Section 222(2) states that the Chief Privacy Officer shall assure
that information is handled in full compliance with the fair information practices as set out in the
Privacy Act of 1974.6
In response to this obligation, the DHS Privacy Office developed a set of Fair Information
Practice Principles (FIPPs) from the underlying concepts of the Privacy Act to encompass the full
breadth and diversity of the information and interactions of DHS.7 The FIPPs account for the nature

and purpose of the information being collected in relation to DHS’s mission to preserve, protect,
and secure.
DHS conducts Privacy Impact Assessments on both programs and information technology
systems, pursuant to the E-Government Act of 2002, Section 2088 and the Homeland Security Act
of 2002, Section 222.9 Given that CBP One™ is a portal rather than a particular information
technology system, this PIA is conducted as it relates to the DHS construct of the FIPPs. This PIA
examines the privacy impact of CBP One™ as it relates to the FIPPs.

1. Principle of Transparency
Principle: DHS should be transparent and provide notice to the individual regarding its
collection, use, dissemination, and maintenance of PII. Technologies or systems using PII must be
described in a SORN and PIA, as appropriate.
CBP One™ is a publicly available mobile application available for Android and iOS
mobile devices in the Google Play or iTunes mobile application stores. To promote transparency,
and provide notice to the public of this new mobile portal to CBP services, CBP published a press
release when CBP One™ was launched to the public.10 The release detailed the functions available
at launch as well as the functions that CBP plans to roll out in the future. CBP is also working with
industry to provide additional information about CBP One™. CBP will continue to provide
information to the public through the use of flyers and outreach to industry groups. CBP may
conduct targeted outreach for specific functions, and may conduct standalone, function-specific
PIAs for new functions as necessary for additional transparency.
There is no privacy risk to transparency; CBP One™ is public-facing and voluntarily
available for the public to use.

2. Principle of Individual Participation
Principle: DHS should involve the individual in the process of using PII. DHS should, to
the extent practical, seek individual consent for the collection, use, dissemination, and
maintenance of PII and should provide mechanisms for appropriate access, correction, and
redress regarding DHS’s use of PII.
Anyone may voluntarily download CBP One™ from the mobile application store on his or
her mobile device. While CBP One™ is limited in its initial functionality, it is available for any

traveler or entity that needs to interact with CBP, so long as the mobile application supports the
function that the user is trying to complete.
In addition, CBP One™ contains a privacy policy that appears every time a user logs in.
Users must consent to the terms of using the application prior to being authorized to use it. CBP
reserves the right to make changes to the privacy policy by giving notice to its travelers on the
CBP One™ Mobile App privacy policy page, and by ensuring protection of PII in all cases. CBP
strongly recommends visiting the CBP One™ Mobile App privacy policy page, and referring to
the dates of the modification. Additionally, CBP will place a banner notice on the app landing page
to notify users that CBP has updated the privacy policy. Depending on the functionality, if
applicable, CBP One™ also uses “just-in-time” notifications that require users consent before the
application can access camera or GPS functions, for example.
Some functions of CBP One™ allow users to submit information on behalf of other people.
This may include a family member submitting information on behalf of another, to the extent
authorized by law. For example, a parent could submit an exit or request travel history on behalf
of his or her minor child. In other functions an operator or International Organization may collect
information from individuals and submit that information to CBP, through CBP One™. For
example, a bus operator may collect information from travelers and submit that information to
CBP through CBP One™ in order to report the traveler’s entry or an International Organization
may collect information on behalf of aliens seeking admission to the United States, typically as
part of a formalized program such as MPP. International Organizations and Operators are
responsible for notifying individuals about information collected and submitted to CBP through
CBP One™.
Because CBP One™ does not store any information, there are no records to correct or
amend. If users submit incorrect information through CBP One™ they can resubmit new
information or contact the CBP INFO Center online or by calling 1-877-CBP-5511 to determine
how to update their submission. Additionally, travelers may request information about records
contained in the source systems that CBP One™ populates through procedures provided by the
Freedom of Information Act (FOIA) (5 U.S.C. § 552) and the access provisions of the Privacy Act
of 1974 (5 U.S.C. § 552a(d)) online at https://foia.cbp.gov/palMain.aspx or by writing to:

When seeking records, the request must conform to Part 5, Title 6 of the Code of Federal
Regulations. An individual must provide his or her full name, current address, and date and place
of birth. The individual must also provide:
•
•
•

An explanation of why the individual believes DHS would have information on him or
her;
Details outlining when the individual believes the records would have been created;
and
If the request is seeking records pertaining to another living individual, a statement
from that individual certifying his or her agreement for access to his or her records.

The request must include a notarized signature or be submitted pursuant to 28 U.S.C. § 1746,
which permits statements to be made under penalty of perjury as a substitute for notarization.
Without this information, CBP may not be able to conduct an effective search and the request may
be denied due to lack of specificity or lack of compliance with applicable regulations. Although
CBP does not require a specific form, guidance for filing a request for information is available on
the DHS website at http://www.dhs.gov/file-privacy-act-request and at http://www.dhs.gov/filefoia-overview.
Privacy Risk: There is a risk that a user could submit information about another
individual(s), without receiving prior consent from the individual(s).
Mitigation: This risk is partially mitigated. Although CBP cannot prevent users from
submitting information for other users, there is no discernable benefit for a user to do so.
Additionally, the user would have to have access to another person’s biographic information and
in some cases, travel documents. Some functions of CBP One™, like the I-94 mobile application,
also require users to submit photographs of themselves and co-travelers. CBP is able to verify if
the photograph is of a “live” person; if it is not, the transaction cannot proceed.
In addition, specific privacy risks related to individual participation will be addressed in
standalone, function-specific PIAs.

3. Principle of Purpose Specification
Principle: DHS should specifically articulate the authority which permits the collection of
PII and specifically articulate the purpose or purposes for which the PII is intended to be used.
CBP One™ allows users to interact with CBP for a variety of purposes. Regardless of
function, users will have to provide basic biographic and contact information in order to use the
application. Brokers/carriers/forwarders have to submit business information, such as company
name and importer ID, in addition to the user’s own biographic information, such as name and
email address, in order to schedule inspections. CBP One™ users reporting exit and entry
information will provide additional biographic information that CBP will use to verify identity and
identify derogatory information. With user consent, CBP One™ may also capture geolocation

Privacy Impact Assessment Update
CBP/PIA-068 CBP One™ Mobile Application
Page 8

information from users’ devices. Different functions may also require users to submit “live”
photographs of themselves. The standalone, function-specific PIAs will fully discuss the
information CBP uses to perform the required function.
CBP One™ allows users to perform a variety of functions. Because the profile creation is
done through Login.Gov, CBP One™, as an umbrella application, does not store information on
users. Consistent with the Import Information System SORN,11 brokers/carriers/forwarders can
submit information to and interact with CBP to schedule cargo inspections. CBP’s Border Crossing
Information (BCI)12 and Arrival and Departure Information System (ADIS)13 SORNs govern the
information CBP One™ users provide when attempting to enter and exit the United States. CBP’s
Automated Targeting System (ATS),14 Border Patrol Enforcement Records (BPER),15 and the U.S.
Customs and Border Protection TECS16 SORNs govern the information undocumented individuals
provide through CBP One™ to verify their enrollment in MPP.
Specific privacy risks related to purpose specification will be addressed in standalone,
function-specific PIAs.

4. Principle of Data Minimization
Principle: DHS should only collect PII that is directly relevant and necessary to
accomplish the specified purpose(s) and only retain PII for as long as is necessary to fulfill the
specified purpose(s). PII should be disposed of in accordance with DHS records disposition
schedules as approved by the National Archives and Records Administration (NARA).
The retention of information CBP collects through CBP One™ depends on the function
the individual is using. CBP uses information collected through CBP One™ to populate existing
CBP systems. For example, information provided by brokers/carriers/forwarders to schedule
inspections is stored in a database within the Automated Commercial Environment for 1 year in
accordance with the Import Information System SORN. Whereas information used to report a
traveler’s exit from the United States may be stored in ADIS for 75 years.

Specific privacy risks related to data minimization will be addressed in standalone,
function-specific PIAs, including the relevant data retention period for the information. No
information is stored locally on the user’s device or in the CBP One™ application itself.

5. Principle of Use Limitation
Principle: DHS should use PII solely for the purpose(s) specified in the notice. Sharing PII
outside the Department should be for a purpose compatible with the purpose for which the PII was
collected.
CBP uses Login.gov to provide a secure and credentialed way for CBP One™ users to
access the application and its different functions. CBP One™ allows users a single easy to use
portal through which to conduct a variety of transactions with CBP. CBP uses information
provided by brokers/carriers/forwarders to schedule inspection appointments and request
additional information. CBP uses other traveler-provided information in order to vet travelers,
update systems, and display relevant information to travelers. CBP uses geolocation information
to determine whether functions, such as reporting exit and arrival, can be accessed by the user, and
to confirm whether or not the individual is in the 1-mile pertinent radius reporting requirement.17
CBP uses photographs submitted by users in order to validate identity and that the person is “live”,
employing liveness detection capabilities. CBP will publish standalone, function-specific PIAs for
certain functions within CBP One™.
CBP may share information collected through CBP One™ both inside and outside of DHS
consistent with applicable law and policy. However, no sharing will come directly from CBP
One™. Any sharing is done from the system in which the information resides, pursuant to the
applicable SORNs that govern that system and associated information sharing arrangements.
Primarily, CBP would share information collected through CBP One™ for vetting purposes.
Standalone, function-specific PIAs will fully discuss function-specific sharing.
Privacy Risk: There is risk that geolocation information (e.g., latitude, longitude) collected
from users of certain CBP One™ functions may be used by CBP to conduct surveillance on
travelers or to track traveler’s movement.
Mitigation: This risk is fully mitigated. The geolocation information collected from CBP
One™ users will not be used to conduct surveillance or track traveler’s movement. CBP does not
track the location of the traveler’s device beyond the time of submission of the data. At the time
the user submits his or her exit or entry, the device’s GPS is pinged by CBP One™ and the latitude
and longitude coordinates are sent to CBP. The GPS ping is only collected at the exact time the
user pushes the submit button and is used to confirm the traveler’s device is in some cases inside
a certain CBP-defined radius or outside the United States. The latitude and longitude information
17

For inbound vessels, CBP does not allow travelers to report their arrival until they are within 1 mile of the U.S.
border. Similarly, CBP requires travelers to be at least 1 mile outside of the U.S. border to report their exit.

Privacy Impact Assessment Update
CBP/PIA-068 CBP One™ Mobile Application
Page 10

captured is not visible to CBP Officers or Agents. CBP collects the latitude and longitude
information from the GPS ping and uses this information for analytical purposes (e.g., to determine
that the individual is in the 1-mile radius pertinent reporting requirement for the report of arrival
of pleasure boats through CBP ROAM or outside of the United States for exit).
In addition, any specific privacy risks related to use limitation will be addressed in any
standalone, function-specific PIAs.

6. Principle of Data Quality and Integrity
Principle: DHS should, to the extent practical, ensure that PII is accurate, relevant, timely,
and complete, within the context of each use of the PII.
CBP One™ collects information directly from users who are voluntarily using the
application. A user must consent to a Privacy Policy each time CBP One™ launches. Users can
manually enter information or use their device’s camera to scan the Machine-Readable Zone of a
travel document, which will prepopulate information into CBP One™. Depending on the function,
CBP may check information submitted by the user against CBP holdings to verify that the
information matches already existing information. Users have an incentive to provide CBP with
accurate information because users have chosen to voluntarily interact with CBP through CBP
One™ and are seeking some form of service from CBP. Some users may submit information on
behalf of others; for example, a family member submitting information for another family member,
to the extent authorized by applicable law and policy. Additionally, operators may use CBP One™
to submit arrival and departure information for their passengers and crew to the extent authorized.
Operators who submit information about travelers to CBP through CBP One™ are responsible for
notifying travelers about their collection and sharing of the information with CBP. Operators
generally provide this notice during their ticketing process. International Organizations provide
notice to individuals before submitting information to CBP on their behalf.
In some cases, CBP One™ obtains consent from users to view GPS location at time of
submission. This ensures that entries and exits are accurately submitted and prevents users from
attempting to claim they have departed the United States when they are still in the United States.
Additionally, for some functions CBP requires users to submit a photograph of the person whose
information is being captured by CBP One™. CBP uses photographs submitted by its users to
validate identity, match against CBP holdings, and determine whether the photograph is “live”.
The liveness detection capabilities provide validation that an individual is present at the time of
submission.
Privacy Risk: There is risk that users will submit inaccurate information about other
people.
Mitigation: This risk is fully mitigated. Although CBP cannot prevent users from
submitting inaccurate information on behalf of themselves or other people, CBP can verify the

Privacy Impact Assessment Update
CBP/PIA-068 CBP One™ Mobile Application
Page 11

information before retaining it as accurate. It is unlikely that a user will submit inaccurate
information on about another person. Primarily, because there is no benefit in submitting
inaccurate information through CBP One™. In some cases, the submission of the inaccurate
information could subject the user to monetary or legal penalties. CBP verifies that the biographic
information is correct and depending on the function can verify the identity of a person and their
location.
In addition, any specific privacy risks related to data quality and integrity will be addressed
in any standalone, function-specific PIAs.

7. Principle of Security
Principle: DHS should protect PII (in all forms) through appropriate security safeguards
against risks such as loss, unauthorized access or use, destruction, modification, or unintended or
inappropriate disclosure.
The CBP One™ mobile application uses Login.gov to manage users’ authentication by
allowing users to sign in with an email address, password, and multi-factor method, and conduct
identity proofing by verifying an individual’s asserted identity. Login.gov ensures a secure
connection and identity verification when using the CBP One™ mobile application. Individuals
with a Login.gov account can sign into multiple government websites (including CBP One™) with
the same email address and password. Login.gov does not share any information provided by the
user with CBP.
No information is stored locally on the user’s device or in the CBP One™ application itself.
The retention of information CBP collects through CBP One™ depends on the function the user
is using. CBP uses information collected through CBP One™ to populate existing CBP systems.
In turn, the security controls of those systems protect the information. For example, information
provided by brokers/carriers/forwarders to schedule inspections is stored in a database within the
CBP Amazon Web Services (AWS) Cloud East (CACE) and is protected by the CACE security
controls. Additionally, CBP has analyzed the application to ensure that information is sent only to
CBP and the application can only access the information necessary to complete the functions.

8. Principle of Accountability and Auditing
Principle: DHS should be accountable for complying with these principles, providing
training to all employees and contractors who use PII, and should audit the actual use of PII to
demonstrate compliance with these principles and all applicable privacy protection requirements.
CBP employee access to the CBP One™ system is limited to users from CBP’s Office of
Information Technology (OIT) in order to perform application updates and correct any issues. CBP
One™ only stores the users Login.gov email address locally onto the user’s device. All other
information submitted by the user through CBP One™ is sent to existing CBP source systems.

Privacy Impact Assessment Update
CBP/PIA-068 CBP One™ Mobile Application
Page 12

The CBP source systems where information is stored maintain their own auditing and
accountability capabilities that will be more fully explained in the appendices as functions launch,
as well as in any standalone, function-specific PIAs. Further, all CBP employees are required to
complete the DHS Security Awareness Training Course and privacy training which explains how
to properly handle and protect PII.

Conclusion
The CBP One™ mobile application is a secure, mobile portal for the public to conduct
various transactions with CBP. In its initial phase, CBP One™ is operational for users to schedule
an agricultural inspection or report their departure from the United States, in accordance with law.
CBP One™ will continue to expand to become the unified mobile portal for public transactions
with CBP. CBP conducted this overarching PIA to describe the risks and mitigations associated
with CBP One™; however, due to broad and disparate functions contemplated for CBP One™,
CBP will also conduct standalone, function-specific PIAs for certain privacy-sensitive functions.
CBP will add links and summaries of each new functional PIA to the Appendices as they are
published to ensure transparency on all publicly available CBP mobile applications.

APPENDIX A: Travelers
I-94 Mobile
I-94 Mobile is function of CBP One™ and offers the same features as the current CBP I94 website (i.e., allows nonimmigrant aliens to apply for a provisional I-94, pay in advance of
arrival for an I-94, retrieve their most recent I-94, view their travel history, and check their
authorized period of stay on any active I-94). I-94 Mobile provides the convenience to capture
travel document information via an optical character recognition scan to auto-populate the
information into the travel document fields when adding one’s travel document information.
Additionally, I-94 Mobile will provide a traveler the ability to self-report the traveler’s exit
from the United States. CBP plans to pilot the self-reporting exit feature in Spring 2021, at select
locations along the Northern Border. The population that can volunteer to use the I-94 Mobile
features for self-reporting departures is limited to I-94 travelers who have come temporarily to the
United States and are exiting the United States at the Pacific Highway and Peace Arch Border
Crossing located in Blaine, Washington; the Champlain-St. Bernard de Lacolle Border Crossing
located in Champlain, New York; and the Ambassador Bridge and Detroit-Windsor Tunnel located
in Detroit, Michigan. CBP is conducting the pilot at these locations on the Northern Border due to
CBP’s partnership with the Canadian Border Services Agency (CBSA). If successful, CBP hopes
to expand the Self-Reporting Mobile Exit (SRME) function of I-94 Mobile to the Southern Border
to increase the accuracy of CBP exit records. CBP will publish a standalone, function-specific PIA
that discusses the SRME function in more detail and also update the existing I-94 PIA series to
include the CBP One™ mobile application as a way in which individuals can apply for and check
their I-94s.

Reporting Offsite Arrival-Mobile (ROAM)
The ROAM mobile functionality is embedded into the CBP One™ Mobile Application,
and provides travelers arriving to the United States with an option to voluntarily self-report their
arrival to CBP. In addition, the ROAM mobile functionality will automate existing manual data
entry and law enforcement queries for CBP and provide a more sophisticated capability for
conducting a remote inspection via video conference. This function will not be available at launch
of CBP One™; CBP will publish a standalone, function-specific PIA to discuss the privacy risks
and mitigations thoroughly. CBP will update this Appendix when the standalone PIA is published.

Application, and provides brokers, importers, and travelers the option to voluntarily schedule
inspection appointments and assist in the management of appointments related to CBP cargo
services.

APPENDIX C: Non-Governmental Organizations
Migrant Protection Protocol
In early 2019, CBP began implementing the Migrant Protection Protocol (MPP),18 which
is a U.S. government action whereby certain foreign individuals, without proper documentation,
entering or seeking admission to the United States from Mexico are returned to Mexico to wait
outside of the United States for the duration of their immigration proceedings. In January 2021,19
the United States ended new enrollments into MPP and began the process of permitting foreign
individuals previously in MPP to be processed into the United States. In order to enroll individuals
in MPP, CBP used Unified Secondary20 and e321 to collect a photograph and biographic
information from the individual. CBP stores this information in a CBP database in the Enforcement
Integrated Database (EID).22
CBP is working with International Organizations (IO), identified by the United States
Department of State, to verify individuals enrolled in MPP whose proceedings under section 1229a
of the Immigration and Nationality Act remain ongoing to streamline their processing into the
United States. Users working for an IO will download and access CBP One™ in the same manner
as all other users of CBP One™. CBP will determine whether a user can have access to IO
functions in CBP One™ based on the information the user inputs to create a Login.gov account.
Eligible IOs will provide email domain names to CBP and CBP will open access to the
functionality within CBP One™ to users who created Login.gov accounts using that email domain.
For example, the International Organization for Migration, a designated IO, may give CBP their
email domain as @iom.int. CBP would then allow any user who created a Login.gov account using
a @iom.int email to view the IO functionalities.

Once a user has access to the IO functionality in CBP One™, he or she will be able to use
the application to facilitate processing of individuals that are enrolled in MPP and have an active
immigration proceeding (i.e., no final adjudication). To do this, an IO user, with the consent of
and on behalf of the individual, will take or upload an existing photograph of the individual into
CBP One™. Once the user submits the information, CBP One™ will attempt to match the image
against a pre-staged Traveler Verification Service (TVS)23 gallery that is populated with all of the
images from the MPP EID database. If a match is made, CBP will send the biographic information
(e.g., first and last name, date of birth) associated with the EID image to the U.S. Citizenship and
Immigration Services’ Person Centric Query System (PCQS)24 to verify that the individual still
has a pending case before an immigration judge. Individuals with a final immigration adjudication
are not eligible to continue MPP processing. Once both the EID and PCQS search are complete,
CBP sends a response back to the IO CBP One™ user which is either a green check mark, a yellow
bar, or a red “X”. Additionally, the user may receive a system error message.

A green check mark indicates that the individual, whose picture the user submitted to CBP, is
enrolled in MPP and has a pending case before an immigration judge. A yellow bar indicates that
the individual is enrolled in MPP, but the individual’s immigration case is now closed, which
makes them ineligible for processing into the United States as an MPP enrollee or that CBP was

unable to locate an immigration case for the individual. The IO can then check the U.S. Department
of Justice's Executive Office for Immigration Review website to determine the case status and if
the information CBP provided through CBP One™ is accurate. A red “X” means that CBP was
unable to locate MPP enrollee information in CBP’s MPP database in EID.
If they receive a red “X” the IO can submit an alien identification number (A-number) as
an alternative method of search. Additionally, the IO user can select a “decline to provide” button
when asked to provide a photograph of the individual which will allow the IO user to submit the
individual’s A-number, with consent of the individual. The A-number query will be sent to EID
and PCQS to try and locate information in those systems associated with the A-number. Like with
the photograph submission, based on the record located CBP then sends a response back to the IO
CBP One™ user with either a green check mark, yellow bar, or a red “X”. If the IO receives
another red “X”, the final option will be to collect biographic information (e.g., first and last name,
and date of birth) from the individual using CBP One™.25 The biographic information is also
submitted to EID and PCQS to locate matching records. As with the previous queries, CBP then
sends a response back to the IO CBP One™ user with either a green check mark, a yellow bar, or
a red “X”. Along with the green check mark CBP will also provide the date the MPP enrollee was
enrolled in MPP. This will assist the IO in prioritizing MPP enrollees to present to CBP for
processing into the United States.
No information is stored locally on the user’s device. CBP does not store the photo but will
store the A-number and biographic data, if provided, in a CBP Amazon Web Services Cloud
Service (CACE) database for 365 days. This data will be retrievable by CBP employees in the
CBP Office of Information Technology in order to provide CBP leadership with anonymized
statistics related to workload and record location ability. For example, CBP employees will be able
to view number of submissions and number of submissions that required submitting the A-number
and biographic data.
CBP is publishing a separate programmatic MPP PIA that will discuss the privacy risks
and mitigations surrounding all aspects of the MPP program, including this use of CBP One™.

25

Initially, the option to input biographic information will not be available and IOs will only be able to use facial
comparison and A-number inputs. CBP plans to quickly implement the biographic input option upon roll-out of this
initiative.
