准备去一个实验室做RA，那么就要换J1签证；
但是明年还准备转校，还要换回F1签证；
不知道这种频繁的换签证是否会对以后申请绿卡造成不良影响？
把F1换成J1之后，再换回F1会不会遇到麻烦？
谢谢！ | t********g

country for 2 years if you apply for F visa ( for studying) but not H visa (
for working) even if your are subject to the two year residence requirement
( please check 212e list). However, you can not change your visa type within
US unless you do the waiver even for F visa. But it may be different from
fields to fields, please ask the counselor in your university to make sure. |
