Anyone has any visa stamp experiences in Canada, I was here in F-1, I changed to H4 then H1 currently, I have been here about 9 years, never has chance to return home.
My questions:
(1) How long does one visa stamp will be valid? Can I use it for multiple entrance?
(2) Is it easy to get visa stamped in Canada?
(3) If I was rejected, can I still come back USA?
(4) If I was rejected, can I still apply for it again in China? Thanks.
