Form I-129F is the petition to bring your fiancé(e) to US to marry within 90 days and apply for green card.
Who applies
- US citizen only. LPR (green card holder) CANNOT use this — they use I-130 + marriage visa.
- Must be legally free to marry (divorced, widowed, single)
- So must your fiancé(e)
- Must have met in person within last 2 years (cultural/religious exceptions)
USCIS fee 2024
- $675 ($535 + $140 biometrics, updated April 2024) — verify uscis.gov/i-129f
- NO fee waiver available for I-129F
Processing time (2024)
- 6-12 months USCIS + 3-4 months consular processing
- Total: 9-15 months from filing to US arrival
Key relationship evidence
- Photos together (multiple events, various dates)
- Communication records (messages, emails, calls) — document months
- Sworn statements from witnesses
- Proof of in-person visit within 2 years
- Sworn statement of marriage intent from BOTH
After I-129F approval
- Case transfers to NVC, then to US consulate in fiancé(e)’s country
- Fiancé(e) does consular interview
- Receives K-1 visa, enters US
- You have 90 days to marry in US (no exceptions)
- After marriage, fiancé(e) applies for green card via I-485
Common errors
- Wrong marital status box
- Photos lacking context (no dates/places)
- Forgetting in-person visit evidence
- Skipping I-134 Affidavit of Support (will need I-864 at AOS)
If your fiancé(e) is already in US
Don’t use K-1. If legally in US (valid visa), marry and use AOS via I-130 + I-485.
