"Are you a B-2 visitor applying to extend your stay, or are you applying to change your status to that of an F-1 or M-1 student? "
这个问题的的前半部分,我应该选YES, 后半部分应选NO。 有些糊涂了。还是我理解有误。
-You can not e-file the B2 extension, but use paper-filing. See this e-filing of I-539 and you can see there is not e-filing of B2 extension available:
