US Immigration law allows two methods for US citizens to bring future spouses to the United States: the K-1 Fiance Visa and the Alien-Spouse Immigrant Visa. The K-1 Visa. generally takes less time to process than the Alien-Spouse Visa. The Alien-Spouse Visa, however, is a proven path toward lawful permanent residency for your spouse.
Steps

Documents
