Got it in the mailbox today. Going for landing this weekend. Which border near Calgary will be the best to go to? And is Saturday a good day to go for landing (flagpoling)?
No you dont need a visa, you can show inform American authorities about your purpose to cross the border and they will send you back with an "entry refusal" document.
Don't worry about it. In my COPR, both my Original entry date and Most recent entry date were wrong (I had travelled before and after both dates). I pointed this to the CBSA officer and she said it's fine. They're really not very concerned about this. Just make sure to note the error to them, and if they decide it needs to be corrected in the document, they will print out a new one for you. Most likely they won't care though.
