How to confirm your case is at the TSC

The receipt prefix can identify where USCIS originally receipted a filing. It does not prove which office currently holds the case.

Your receipt number starts with:
SRCXXXXXXXXXX
= Receipt origin associated with Texas Service Center; verify current handling separately

Transfers do not change the receipt number. Check your USCIS account or transfer notice for the current office. See all service centers for Form N-400 →

Frequently asked questions

How long does Form N-400 take at the TSC in 2026?+
GreenLight does not publish a hand-authored Texas Service Center estimate for Form N-400. Use the official USCIS tool and select the exact form, category, and office.
How do I know if my Form N-400 is at the TSC?+
A SRC prefix can identify where USCIS originally receipted the filing. It does not prove which office currently holds the case, and a transfer does not change the receipt number. Confirm current handling in your USCIS account or transfer notice.
What does a SRC receipt number mean?+
SRC identifies a receipt-number origin associated with Texas Service Center. It is not a live routing code for the office currently holding the case. IOE is an electronic-processing prefix, not a service center.
Is the TSC faster or slower than other USCIS service centers?+
Processing times vary by form type and current workload. GreenLight does not rank service centers by speed. Check the official USCIS processing-time page. Always check the official USCIS processing times page for the most current estimates.
Can I request expedited processing of my Form N-400 at the TSC?+
Yes. USCIS allows expedite requests for qualifying situations: severe financial loss, urgent humanitarian reasons, US government interests, or USCIS error. Submit your request through your online USCIS account or by calling 1-800-375-5283.
