Quick answer: Not married yet → K-1 fiancé visa (file I-129F). Already married → CR-1/IR-1 spousal visa (file I-130). The decision starts there. Everything else — cost, speed, risk — is secondary to your legal status as a couple.
The Core Difference
The K-1 and CR-1 are both paths that bring a foreign partner to the U.S. permanently — but they start from different places in the relationship and involve different legal sequences.
Not married yet
U.S. citizen petitions for their foreign fiancé(e). The foreign partner enters the U.S., marries within 90 days, then applies for a green card from inside the country.
Already married
U.S. citizen or green card holder petitions for their foreign spouse. The foreign spouse enters the U.S. directly as a permanent resident — no post-arrival adjustment needed.
Full Side-by-Side Comparison
| Factor | K-1 Fiancé Visa | CR-1 / IR-1 Spousal Visa |
|---|---|---|
| Eligibility | Not married; U.S. citizen petitioner only | Already married; U.S. citizen or LPR |
| Starting form | I-129F (Petition for Alien Fiancé) | I-130 (Petition for Alien Relative) |
| Where to marry | Inside the U.S., within 90 days of entry | Already married before filing |
| Time to U.S. entry | ~9–15 months | ~14–24 months |
| Green card on arrival | No — must file adjustment of status after wedding | Yes — enters as conditional or full LPR Advantage |
| Total to green card | ~21–40 months | ~14–24 months Faster |
| Visa fee | $675 (I-129F) + $265 (MRV) | $675 (I-130) + $325 (IV fee) |
| Adjustment of status | Required after marriage (~$1,440) | Not required — arrives as LPR |
| Total gov. fees (approx.) | ~$2,580–$2,880 | ~$1,500–$1,800 Cheaper overall |
| Work authorization | Not included — must apply for EAD after marriage | Included on arrival as LPR Advantage |
| Travel while pending AOS | Requires Advance Parole (separate application) | N/A — already a permanent resident |
| Conditional green card | Yes — 2-year conditional if married <2 years | Yes — CR-1 if married <2 years; IR-1 if 2+ years |
| Children included | K-2 derivative visa (filed together) | IR-2 / CR-2 derivative visa |
| Interview location | U.S. embassy abroad (fiancé only) | U.S. embassy abroad (spouse only) |
| Risk if denied at interview | Higher — relationship not yet legally formalized | Lower — marriage certificate provides baseline proof |
Cost Breakdown: K-1 vs CR-1
The K-1 appears cheaper upfront, but once you add the adjustment of status filing after the wedding, total government fees end up comparable — and CR-1 is slightly cheaper overall.
| Fee Item | K-1 Path | CR-1 Path |
|---|---|---|
| Petition filing fee | $675 (I-129F) | $675 (I-130) |
| Visa application (MRV / IV) | $265 | $325 |
| Medical exam | $200–$500 | $200–$500 |
| Adjustment of status (I-485) | $1,440 | — |
| USCIS Immigrant Fee | — | $235 |
| Total (gov. fees only) | ~$2,580–$2,880 | ~$1,435–$1,735 Cheaper |
Attorney fees, document translation, and travel costs are additional for both paths and can add $1,500–$4,000 depending on complexity.
Which is Faster: K-1 or CR-1?
This is the most common question — and the answer depends on what you're measuring.
Faster to reach U.S. soil: K-1 (slightly)
The K-1 petition at USCIS takes roughly the same time as the CR-1 I-130, but the K-1 skips the NVC document submission stage that the CR-1 requires. This makes the K-1 slightly faster to the point of U.S. entry — typically 9–15 months vs 14–24 months for CR-1.
Faster to green card: CR-1 (clearly)
The CR-1 winner arrives already a permanent resident. The K-1 winner still needs 12–24 months of adjustment of status after the wedding. When you count the full path from filing to green card in hand:
- K-1 total: ~21–40 months
- CR-1 total: ~14–24 months
Bottom line on speed: If you want to be together in the U.S. as fast as possible and don't mind being in AOS limbo, K-1 gets you there slightly sooner. If you want a green card in hand faster, CR-1 wins — you arrive as a permanent resident.
