The entire process of filing the petition for a K-1 visa until the time the visa is signed can take six to nine months, AllLaw notes. The U.S. Embassy generally takes up to three months just to process the visa depending on how many other applications the embassy is processing.
The K-1 visa is a visa the government issues to someone who is engaged to a United States citizen, and the visa allows that person to enter the United States, AllLaw notes. Once the individual receives permission to enter the country, he can get married. The marriage must take place within 90 days of the date of entry into the United States.
