USCIS Fax Number — Fax Immigration Documents and Forms

USCIS does not publish one general fax number, because intake is split across service centers in Nebraska, Texas, California, and Vermont, and the right number depends on which center holds your case. Fax is most relevant for responding to a Request for Evidence or sending supporting documents on a pending application, and the RFE notice itself usually names the fax number or address to use. For most other filings, USCIS pushes applicants toward online accounts in myUSCIS rather than fax.

What You Can Fax to USCIS (Immigration)

Tip: Print your receipt number, which begins with a prefix like IOE, EAC, or WAC, and your A-number on every page so the right file is updated. The fax number for an RFE response is stated on the RFE letter, so read that notice carefully rather than guessing at a service center number. Send a clear cover page that states the document is an RFE response and lists the form type. After faxing, follow up through your myUSCIS account or by calling the Contact Center to confirm the response was logged, and keep the Send FAX Mail confirmation in your records.

Faxing to USCIS (Immigration) — FAQ

USCIS routes cases through the Nebraska, Texas, California, and Vermont service centers, and you fax the one processing your case. The receipt number prefix on your notice indicates which center holds the file, and an RFE letter will state the exact fax number to use.

Yes, RFE responses are one of the main things USCIS accepts by fax. Use the number printed on the RFE notice, include your receipt number and A-number, and label the cover page clearly as an RFE response.

Put your receipt number and A-number on every page so USCIS can match the fax to your pending case. Without those identifiers, a fax can be hard to associate with your file and may delay processing.
