回复：Quesion- H1 travel to Canada ?

If you need to go back to china, a valid h1b visa stamped on your passport is a must. but if you only travel to canada and return in a month, you don't have to have your h1b visa stamped on your passport, a valid i-94 is fine. But of course you need a visitor visa to enter Canada. Again, if you go back to china and wanted to return to US. you have to have your H1 visa stamped on your passport, good luck.
