Can a K-1 Visa Holder Leave the United States?
The K-1 visa allows a fiancé(e) to enter the United States one time only. If you leave the United States after entering on a K-1 visa, you may not re-enter on the same visa. If you want to leave and re-enter the United States, you should apply with Form I-131 Application for Travel Document to the USCIS office that serves the area where you live for advance parole to return to the United States. See Emergency Travel for information on how to get a travel document that allows you to return to the United States.
