Starting November 13, 2023, the Potomac Service Center (PSC) will no longer accept mailed correspondence. All mailed correspondence intended for cases processed by the PSC must be mailed to the Texas Service Center (TSC) as of that date, unless otherwise noted.

To avoid processing delays, USCIS said, applicants and their representatives should instead upload their responses to their USCIS online accounts (for receipt notices that start with IOE-) or mail them to the Texas Service Center at:

USCIS Texas Service Center
Attn: Digital RFE
6046 N Belt Line Rd. STE 114
Irving, TX 75038

USCIS strongly encourages use of an USCIS online account and self-service tools to upload responses for all online cases.
