Does USCIS Accept Faxes? What to Do Instead

For almost every standard USCIS filing, the answer is no -- USCIS processes forms and petitions by mail or through myUSCIS online filing, not by general-purpose fax. The exception: if USCIS has already sent you a specific letter (a Request for Evidence, a Notice of Intent to Deny, or similar) that includes a fax number and tells you a fax response is acceptable, you can send that one online without a machine.

This guide covers how to tell the difference, how to send the fax if you're in that narrow case, and what to do if you're not.

First: check whether USCIS actually wants a fax from you

Don't guess a fax number and send something speculatively -- USCIS's default intake for nearly all forms is mail (to the correct service center or lockbox address for that specific form) or myUSCIS online filing for eligible forms. General case-status questions and most petitions do not go by fax at all.

The one reliable signal that a fax is appropriate: your own USCIS notice or letter explicitly provides a fax number and says you may respond by fax. If that's what you have in hand, keep reading. If you don't have that, faxing is very unlikely to be the right move -- follow the mail or online instructions printed on your form or notice instead.

If your notice provides a fax number, send it online (no machine, no subscription)

Full disclosure: we make Just The Fax. Pay from $1.99 per fax (tiered by page count), no account, no subscription, nothing to cancel -- send-only, it does not receive faxes.
  1. Have your response document ready as a PDF or a clear photo of each page.
  2. Go to justthefax.io -- no signup required.
  3. Enter the exact fax number printed on your USCIS notice (not a general USCIS number found elsewhere -- see below).
  4. Upload your document, add any cover sheet the notice requested, and send.
  5. Keep your delivery confirmation with your case file.

What you need before you send it

  1. Your document as a PDF or clear photo. Every page straight, in focus, and readable.
  2. The exact fax number from your USCIS notice. This is the one detail that matters most -- USCIS fax numbers, when they exist for a case, are specific to the service center and sometimes the individual notice. Never reuse a number from an older letter or a different case type.
  3. Your receipt number and any cover-sheet information the notice asked you to include, so the response can be matched to your case.

When USCIS actually allows a fax

  • Responding to a Request for Evidence (RFE) or Notice of Intent to Deny (NOID) -- only when that specific notice provides a fax number and states a fax response is accepted.
  • A Form G-28 (attorney appearance) sent to a specific service center, when an attorney has been instructed to fax it for that case.
  • A rare expedite or biometrics-reschedule request, only when a USCIS officer or notice has given you a fax number directly for that purpose.

Outside of these, assume fax is not the channel USCIS wants and use the mail or myUSCIS instructions on your form instead.

Frequently asked questions

Does USCIS accept faxes for general filings like I-130 or I-485? No. Standard petitions and applications go by mail to the correct lockbox address or through myUSCIS online filing, not by fax.

How do I know if I'm allowed to fax USCIS? Only if a USCIS notice or letter you received explicitly gives you a fax number and says a fax response is accepted. If you don't have that in writing, don't fax -- use the filing method on your form's instructions.

What if I don't have a fax number from USCIS? Don't guess or search for a general USCIS fax number online. Follow the mail or online filing instructions for your specific form instead.

Can I fax USCIS without a machine if I do have a valid fax number? Yes -- upload the document from your phone or computer and send it online, no fax machine or account required.

Will I get confirmation that USCIS received my fax? You'll get delivery confirmation that the fax transmitted to the number you entered. Keep that confirmation with your case records; USCIS does not typically send a separate fax acknowledgement.
