I'm gonna go travel to Mexico this may 4th, and I just want to know if PR card is enough proof to go to Mexico and back to Canada after a week? My passport is from my home country and not from Canada. Would it be okay?
If you are Canadian PR you don't need any visa for Mexico. Just show your PR card to the mexican officer.
