USCIS Faxing FAQ
What to know before faxing immigration documents.
- Can I fax documents to USCIS?
- USCIS generally prefers online uploads (MyUSCIS) or mail. Some workflows may provide a fax number for urgent supporting documents—only use the number and instructions provided for your case.
- How do I format a USCIS fax?
- Single PDF: cover sheet → case notice/receipt → your documents. Include receipt number, names, DOB, and any A‑Number on the cover. Use clear scans and page numbers.
- Is it secure to fax immigration documents?
- Use a trusted service with encryption in transit, avoid public Wi‑Fi, and minimize PII on the cover page. Always verify the destination number from official correspondence.
- When should I fax USCIS?
- Send during business hours for the office handling your case. For time-sensitive RFEs/NOIDs, follow the notice instructions exactly.
- My USCIS fax failed. What next?
- Confirm the number and identifiers, resend as a clean PDF, and retry within business hours. See troubleshooting.
