USCIS fax numbers vary by form type and filing location. Most forms are filed by mail to a USCIS Lockbox. Fax is used for specific correspondence, RFE responses directed by an officer, and attorney communications. Always check your notice or uscis.gov for the correct number before faxing.

Frequently asked questions
Why does the submission date matter for USCIS filings?
USCIS RFE and NOID deadlines are firm — missing them typically results in denial of your application. The certified receipt proves the exact date your response arrived at the designated fax number, not just when you sent it, providing independent evidence of timely filing.
Where do I find the USCIS fax number for my case?
For RFEs and NOIDs: use the fax number printed on the notice itself — each notice specifies where to send the response. For G-28 filings and attorney correspondence: use the fax number for the specific field office or service center handling your case, available at uscis.gov/about-us/find-a-uscis-office.
What is a SHA-256 certified receipt?
When your fax is delivered, FaxSeal generates a receipt with the SHA-256 cryptographic hash of your exact document, the fax number dialed, and the confirmed delivery timestamp. The hash ties the receipt permanently to that specific file — verifiable by anyone at faxseal.com/verify.
Can an immigration attorney use this for multiple clients?
Yes. FaxSeal credits never expire — buy a bundle for your firm and use across all clients. Each fax generates its own certified receipt with a unique verify URL, giving you per-client proof of USCIS filing for your case files.
Can I sign immigration forms and fax them in one step?
Yes. Use the Sign & Fax tool — draw your signature, place it on the form, and fax directly from the same screen. No printing, no scanning, no fax machine required.
What if the fax fails to deliver before a deadline?
You are never charged for an undelivered fax. Retry immediately if delivery fails near a deadline. For critical USCIS deadlines, consider sending certified mail as a backup and contact USCIS to document your attempts.
