I warn the caveats in the thread above, and it still may be worth consulting a lawyer, or waiting until you have good docs of being in Canada, etc.This is so helpful. Thank you!
Because as has been pointed out - logically - what is written in the books and procedures is a decent starting point, but practice unfortunately unclear. I wish we had more reports of what is actually being done in practice once someone returns to Canada with an R-1 PRTD.
And the consequences are potentially severe if this read of things (above) is incorrect.
