There are various types of U.S. visas. Spouses of U.S. citizens can travel to the United States by applying for a U.S. marriage-based visa. So, how do you apply for a U.S. marriage-based visa? What documents are required for the application? Below is an introduction to the application documents for U.S. marriage-based visas.
The K visa is for the fiancé(e) of a U.S. citizen and their minor unmarried children, stepchildren, or adopted children. Specifically: the K-1 visa is issued exclusively to the fiancé(e) of a U.S. citizen; the K-2 visa is issued to the unmarried children under 21 years of age of the K-1 visa holder, including stepchildren (children born to their previous spouse) and adopted children.
Applying for Permanent Residence After Entry
1. After the fiancé(e) of a U.S. citizen enters the United States with a K-1 visa, the couple must marry within 90 days.
2. After marriage, the K-1 visa holder will be granted "conditional permanent residence" for a period of two years.
3. Within 90 days before the two-year period expires, they must apply to the immigration authorities to become a permanent resident. Conditional residents may also adjust their status while abroad to become formal permanent residents.
