Hi,1) if you return on the same day, how do you apply for the PR card?
PR card application is based on officers discretion. As long as they accept your landing you are good. PR card be later requested with IRCC through call or web form as well.
Do you complete ALL the procedures including PR card, applying for SIN etc? Is it a completely safe option to go back to Canada at a later day?
SIN can be done online and delivered to your US address as well. Check the forum for details on SIN.
If your landing formalities are completed , you are good to enter Canada later via land and via air with PRTD
2) Do you have to go with wife/kids if they are included in the application? We all have same expiration CoPR date in Sept 20.
I went with my family. Everyone must land before their COPR expiry. Extension in COPR is still possible but there are lot of new rules are request are coming from IRCC when you are ready to travel. It depends on your situation to make a call if you want to land now or later when everything has settled down.
3) How did you deal with AirBnb booking and cancel if come back the same day? Do you find cancel easy or any trouble in that?
Since you will mostly be traveling with family, Airbnb is better option than a hotel. Cancelling Airbnb costs you service fee and one night fee cost in most cases or 50% fee. So choose wisely when booking.
You can safely land in Seattle border. Its good as well. Lot of successful landing happened in Seattle border. Check this thread with previous successful landing experience.
Let me know if you still have any questions.
Can I apply for PR card after soft landing? I asked the officer during soft landing but I was told that I can only apply when I go to Canada to settle. Is it possible to apply for PR card to be sent to a Canadian address while I am in the US?
