How to confirm your case is at the CSC

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:
WACXXXXXXXXXX
= Receipt origin associated with California 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 I-131 →

Frequently asked questions

How long does Form I-131 take at the CSC in 2026?+
GreenLight does not publish a hand-authored California Service Center estimate for Form I-131. Use the official USCIS tool and select the exact form, category, and office.
How do I know if my Form I-131 is at the CSC?+
A WAC 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 WAC receipt number mean?+
WAC identifies a receipt-number origin associated with California 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 CSC 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. Use the official selector for the exact form and category. Always check the official USCIS processing times page for the most current estimates.
Can I request expedited processing of my Form I-131 at the CSC?+
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.
