The K-1 visa is designed for the foreign fiancé(e) of a U.S. citizen. To qualify, applicants must submit Form I-129F and demonstrate a genuine relationship with their U.S. citizen partner. There must be a clear intent to marry within 90 days of entering the United States, and typically, the couple must have met in person at least once, although exceptions to this requirement are possible in specific circumstances. The initial period of stay granted is 90 days, during which the couple must marry and file for adjustment of status to pursue permanent residency.

The K-1 visa process involves several fees, including the I-129F petition fee of $535, a consular processing fee of approximately $265, and additional costs for the required medical examination. Adjustment of status fees are incurred after marriage. This process is considered moderately difficult, with the most critical aspect being the provision of compelling evidence to prove the authenticity of the relationship. Visa Agency involvement is helpful to navigate the requirements. Processing times typically range from 6 to 12 months, and the approval rate is approximately 72%.
