It seems pretty extreme to have to wait 30 days then however long after that until the actual appointment. What would be the downside of going to a border whenever you want, and getting it done right away? Am I missing something? I am in a similar situation.
Of course, going to the border will be quick but downsides are:
- If you live near border then no problem, otherwise it could be a long drive or commute through public transportation.
- Few borders have specific days and time for processing PR landing (e.g., Niagara bridges)
- Also, they may process few landings for that day and ask you to come at a later time/day. Rainbow bridge does 10-20 per day and refuse to do more on a specific day.
- Many inland people may not be comfortable doing flagpoling (though it is straight forward). Either they don't have their own vehicle or they don't want to cross the border fully (no US visa situation).
If your COPR is not expiring soon and you are not in hurry, then Inland landing in IRCC office is a good option. Also, they say 30 days but normally your get a response and a landing interview before that. In my case, I sent them an email on 1-March-2019, received a response by mid March for a landing date of 25-March.
