[jack786]

I am on OPT which is expring on june 28th. I have an approved h-1b for a start date of july 1st with a different employer that the one I am currently working with on OPT. I must work till june 28th with this employer. My question is, is it possible for me to go to canada to get a h-1b visa stamp in june? When is the earliest I can go to get the stamp thank you
