So, I completed my landing over the weekend by entering Canada via the Peace Bridge through Buffalo.
I reached the border on July 5 at around noon. At the booth, I was asked to park on the side and go in to get my CoPR signed. Due to the long weekend, it was pretty busy and it took me 2 hours to get out. In the building, after processing my application, I was asked my address where the PR card would be mailed in 8-10 weeks. Also, I was told not to get the card mailed outside Canada, which was a little surprising.
Then, I was asked for my settlement funds document and also to initial next to the answers to questions regarding previous convictions, felonies etc. (the 3 questions on the CoPR).
After the officer signed my CoPR and read my rights as a PR, I was the directed to the customs section where I gave my Accompanying Goods & GTF document and then went to the cashier for the customs receipt.
Next, I went to the Service Canada office located in Niagara and got my SIN. It took me an hour to get out with wait time included.
Coming back to the US via AVR:
I visited Niagara Falls and spent the next 3-4 hours there. I crossed over via the Rainbow bridge into the US and surprisingly at the booth, I was only asked for my passport and i-797 and was let in. I was not asked to get out of the car and the whole process took around 30 seconds.
I was really nervous regarding entering via AVR but I’m very relieved now that its done with.
Thank you everyone for all your help.
