1. Timeline: the K-1 visa may be the faster option.

2. Cost: the total cost of the K-1 visa may be higher due to additional travel expenses and the cost of adjustment of status once the fiance enters the United States.

3. Immigration history: If the foreign fiance has previously overstayed a visa or has a criminal record, it may be more difficult to obtain a K-1 visa. In such cases, a marriage-based green card may be the better option.

4. Relationship history: for a K-1 visa, the couple must provide evidence that they have met in person within the past two years. For a marriage-based green card, the couple must provide evidence of a bona fide marriage.

5. Travel plans: it is easier to travel frequently or live abroad for extended periods of time with a marriage-based green card, which allows for multiple entries and re-entry to the United States.

With a K-1 visa, the foreign fiance will need to apply for adjustment of status to obtain a green card and may face travel restrictions during that process.

It is important to carefully consider each of these factors and consult with an experienced immigration attorney to determine the best option for your specific case. Please book your Zoom call with Katya Stelmakh here: https://stelmakhlaw.com/en/book-a-consultation/
