Hope you get your Passport soon. I did tatkal to be away from this VFS dramas. i understand your situation. You should get it soon. dont worry.
For landing: You need your passport, COPR and make list of goods that you want to bring in while you move so that you can fill them when they ask you to fill the Goods to follow form while landing. Also be prepared to stay there for 14-days. As there is a mandatory quarantine on Canada side once you enter. So make preparations like booking airbnb and getting groceries from Usa(if travelling by road).
while returning to US, your both passports and valid i797A, if you are travelling by road.
Thanks.
Thank you for your response. I really appreciate it. If I tell them I can travel to Canada, will they ask for Passport for CoPR ? What if I dont get the passport in until next month ?
