赴美留学签证哪个类别？
1. 签证类型选择（F，M，J-1) F： for Full time degree seeking students M： for Full Time Non Degree Seeking Students J-1 ：for students participating in exchange programs. If you are coming to the US with your sponsor(the university or institute that is sponsoring your education)， then your visa will be F or M， and if they sponsor only a short course (less than six months duration)， it would be a B-1/B-2 Visa which allows you to attend classes but not study. The main difference between an F， M， & J-1 visas lies on their purpose of stay. An F ， M can legally work as long as there is employment authorization issued by USCIS， however ，a J-1 cannot work off campus unless he has been granted a STEM OPT extension. Another major distinction is that while an F&M student must leave the U.S when his/her status expires; A J-1 stays until its two years residency requirement have been fulfilled.
