Okay so my student visa expires on April 24th and my school trip is on the 27th. I'm currently living in edmonton and my parents have sent out our passports for permanent residence. We are expecting them to come very soon and we plan on going to the border to validate it. But i won't have my Permanent Residency card until after the trip. So even if i get the visa to go on the trip to california, my dad says i won't be able to get back into Canada because i won't have my Permanent Residency card. Is there any way i can possibly go on this trip? I would really appreciate it if someone would reply to this as soon as possible. Thanks
I'm really desperate for an immediate answer. I have to tell my teacher if I can go or not by around next week..
