Find the Correct DHS Headquarters Address, Component Contact and Approved Visitor Route
The Department of Homeland Security building is not a public walk-in service center. DHS headquarters operates from a secure federal campus, while immigration, customs, airport security, disaster aid and cyber reports are handled by separate DHS components.
This guide explains the St. Elizabeths headquarters address, why 2700 and 2707 Martin Luther King Jr. Avenue appear in official records, when the Nebraska Avenue Complex is relevant, how to prepare for an approved visit and which agency should receive your request.

Prepare for a DHS Headquarters Visit Without Being Turned Away
Confirm that the meeting is actually in person
Ask whether the meeting is virtual, at St. Elizabeths, at the Nebraska Avenue Complex or at another DHS component office.
Obtain the host’s full contact details
Save the host’s name, office, phone number and meeting confirmation. The central operator may not be able to replace a missing visitor sponsor.
Ask for the exact building, gate and arrival time
St. Elizabeths is a large secure campus. A street address alone is not enough to identify the correct security checkpoint or destination.
Confirm identification requirements
Bring the valid photo identification specified by the host. Confirm that the name provided for visitor clearance matches the identification exactly.
Request accommodations in advance
Tell the hosting office before the visit when you need mobility, communication, interpretation or other reasonable accommodation support.
Follow all security and device instructions
Secure federal facilities may limit items, photography, recording, parking, drop-offs and electronic devices. Follow the invitation rather than assumptions from another federal building.
Call the host if the arrival instruction fails
Do not move between gates or attempt to enter another campus area without authorization.
Bring
- Meeting confirmation
- Host’s full name
- Host’s phone number
- Exact building or gate
- Accepted photo identification
- Accommodation confirmation
Do not assume
- The campus accepts walk-ins
- 2700 and 2707 are interchangeable entrances
- Parking is publicly available
- A mailed appointment notice applies to headquarters
- Another DHS facility uses the same rules
- The operator can create visitor clearance

Common DHS Mailing Problems and the Correct Fix
Problem |
Why it causes delay |
Best correction |
|---|---|---|
Mail addressed only to “DHS Building” |
No responsible office or component is identified |
Add the office name and Mail Stop |
Using 2700 instead of official mailing instructions |
2700 is the GSA property location for the Center Building |
Use 2707 and the exact Mail Stop when instructed for headquarters mail |
Sending USCIS forms to DHS headquarters |
USCIS forms use form-specific lockbox or filing addresses |
Use the address on the current USCIS form page |
Sending a FOIA request by ordinary mail or email |
DHS changed its FOIA intake procedure in January 2026 |
Use the official online FOIA submission process |
Using the headquarters comment line for a case |
The comment line is not an immigration, disaster or traveler case system |
Contact the responsible component with the case or receipt number |
Submit a DHS FOIA Request Through the Correct Online Component
Important 2026 filing change
Effective January 22, 2026, DHS states that it no longer accepts hard-copy mailed or emailed FOIA and Privacy Act requests for DHS records. Use the official online submission route.
Search already-published records first
Check the DHS FOIA Library, component reading rooms and public reports before filing a new request.
Choose the component that created the record
A USCIS immigration file, CBP travel record, ICE record, TSA record and headquarters policy record may be processed by different FOIA offices.
Describe the record—not only the topic
Include dates, names, locations, record type, case number and the office likely to maintain it.
Complete identity verification when requesting your own records
Follow the online instructions for certification of identity or authorization. Do not upload unrelated sensitive documents.
Save the request number
Use it to check status, communicate with the FOIA office and identify the request in later correspondence.
