Hi guys , i just obtained my open work permit after waiting 4 months from sending my spouse sponsorship application with my wife . i got job offer from canadian company but they told me that their will be several visits to the USA , Is it ok to leave canada and come back after getting the open work permit ? . i came to canada on visitor visa and got extension as visitor . also why is it written at the bottom of the open work permit " This doesn't authorize reentry " ?? ... Thanks alot guyss
