B-2 tourists come to the US to take part in tourist activities such as sightseeing or visiting friends or relatives. Usually, B-2 tourists will be admitted to the US for a maximum of six months, although sometimes it is possible to extend their stay in the US. Our office provides advice and representation to foreign nationals who wish to extend their stay in the US, or to change to a different nonimmigrant (temporary) or immigrant (permanent) category.
