Common mistakes to avoid
- Filing too early or too late — must be in the 90-day window before the card expires
- Submitting weak bona fide marriage evidence — joint accounts, photos, affidavits all help
- Not filing a waiver when filing without the spouse (divorce, abuse, or hardship grounds)
Filing tips
- A pending I-751 extends conditional status for up to 48 months via I-797 receipt
- You can file N-400 while I-751 is pending if otherwise eligible
- In divorce cases, gather evidence the marriage was entered in good faith — not just its duration
