I plan to stop in the United States for a day and take a flight to another country on the next day. Do I need to apply for C-1 visa or a B-1/B-2 visa?
If you seek layover privileges for purposes other than transiting through the United States, such as to visit friends or for sightseeing, then you must qualify for and obtain the type of visa required for that purpose, such as a B-2 visa.
