香港學生去美國留學一般能拿幾年的簽證？

The answer is usually 5 years.

The U.S. Consulate may issue a student visa less than 5 years of validity for several reasons. Usually they are:

1. The length of program (If you are attending a 1-year program, why do you need a 5-year visa?)

2. Risk of the Traveler (The U.S. considers Mainlander are high-risk.)

3. The kind of visa (M-1 usually has less validity than F-1)

美國政府一般比三至五年,但係可以續期的

但係就要小心睇清楚你自己的年期,否則有機會『八人大橋』抬你走

去旅行就十年八年,讀書就三到五年.至於續期就真係要問番美國領事館

希望幫到你啦
