1. Forgetting to Sign Forms

Every USCIS form must be signed.
Missing signatures are a top reason for immediate rejection.

✅ Tip: Double-check every required signature line before mailing or submitting.

2. Using the Wrong Form Version

USCIS regularly updates its forms.
Submitting an outdated version can lead to rejection.

✅ Tip: Always download forms directly from the official USCIS website.

3. Missing Required Evidence

Forgetting to attach necessary supporting documents is a common cause of RFEs.
Examples: Missing marriage certificates, missing passport copies, missing tax returns.

✅ Tip: Carefully follow the checklist in the form instructions.

4. Sending Poor-Quality Copies

Blurry, dark, or incomplete copies of documents can delay your case.

✅ Tip: Always submit clear, legible photocopies — not originals unless requested.

5. Incomplete Information

Skipping a section or leaving important questions blank without explanation can trigger RFEs.

✅ Tip: If a question does not apply to you, write "N/A" or "None" — do not leave it blank.

6. Filing to the Wrong Address

Different forms and eligibility categories require sending to different USCIS addresses.
USCIS may reject or delay your application if it’s mailed to the wrong place.

✅ Tip: Double-check filing addresses in the latest USCIS instructions for your form.

7. Incorrect Fee Amounts

Submitting the wrong filing fee can lead to rejection.
USCIS fees sometimes change, and fees vary by form and situation.

✅ Tip: Use the USCIS Fee Calculator to confirm the correct amount.

8. Bad Check or Payment Method

Incorrectly completed checks, wrong payee, or payment errors can cause rejection.

✅ Tip: Make checks or money orders payable to "U.S. Department of Homeland Security."
(No abbreviations like "DHS.")

9. Moving Without Updating Your Address

USCIS mails important notices to your address on file.
If you move and don't notify USCIS, you may miss critical updates.

✅ Tip: Update your address using Form AR-11 within 10 days of moving.

10. Submitting Incomplete Translations

Any document not in English must have a complete, certified English translation.
Incomplete translations can delay your application.

✅ Tip: Include a translator’s certification statement with translated documents.

Tips for Filing Successfully

Read the form instructions carefully — twice.
Use black ink if filling out forms by hand.
Assemble your package in logical order (application, fees, supporting documents).
Keep a full copy of everything you send.
