USCIS Fax Numbers by Service Center
USCIS routes cases to different service centers based on form type and applicant location. The correct fax number depends on which center is processing your case.
USCIS Lockbox: Evidence / RFE Responses
Assigned per notice
When USCIS issues a Request for Evidence (RFE) or Notice of Intent to Deny (NOID), the response instructions include a specific fax number. This number is unique to your case and service center. Always use the exact fax number from your notice.
National Benefits Center (NBC)
1-913-214-6399
Handles adjustment of status (I-485), employment authorization (I-765), and advance parole (I-131) applications. Primarily used for interview-related document submissions when instructed by an officer.
USCIS Service Center: Texas (TSC)
1-214-962-1625
For cases processed at the Texas Service Center. Used for RFE responses and additional evidence submissions. Confirm your case is at TSC by checking your receipt number (starts with SRC or LIN for transferred cases).
USCIS Service Center: Nebraska (NSC)
1-402-219-6169
For cases processed at the Nebraska Service Center. Common for employment-based petitions (I-140, H-1B). Receipt numbers starting with LIN indicate Nebraska processing.
USCIS Service Center: California (CSC)
1-949-389-3075
For cases processed at the California Service Center. Handles many humanitarian applications and certain employment visas. Receipt numbers starting with WAC indicate California processing.
USCIS SAVE Program (Verification)
1-202-443-0392
The Systematic Alien Verification for Entitlements (SAVE) program fax line. Used by government agencies to verify immigration status for benefits eligibility, not for individual applicants.
Always use the fax number printed on your specific USCIS notice. The numbers above are general references. Your notice may direct you to a different number based on your case type and processing center.

Tips for Faxing USCIS
Immigration deadlines are strict. These tips help ensure your documents are received, matched to your case, and processed on time.
Every RFE and NOID includes a specific fax number and a barcode cover sheet. Use the barcode cover sheet USCIS provides: it routes your response directly to your case file. Without it, your documents may not be matched to your case.
Include your receipt number (e.g., SRC-XX-XXX-XXXXX) on every single page. USCIS processes millions of cases and orphaned pages cannot be reunited with your file.
Do not fax original documents. USCIS cannot return faxed materials. Send originals by mail if the instructions require original signatures or certified translations.
If your RFE has a deadline, fax your response at least 2-3 days early. The fax confirmation timestamp from AvoFax counts as your submission date, but allow buffer for processing.
For large evidence packages (50+ pages), consider sending by mail with tracking AND faxing a copy. This gives you both a delivery confirmation and a mail receipt.
