@Laur****
, come on now, I did not call you a liar :/ I was stating that I've not seen anyone pull off more than two 30 day exempt stamps by a land border since Dec (when the rule came into effect).
And I was suggesting that if people are gonna border-bounce for 30 day visa exempt stamps it can't hurt the have the 3-proof ofs. That you've never been asked doesn't mean you couldn't be asked or that other people haven't been asked. Failure to meet those proof ofz are a valid reason to deny you entry into the country on a visa exempt entry stamp.
All I'm tryin' to do is provide people with accurate up-2-date information about how to minimize the risk of running off the rails visa/extension-wise here in the glorious "Land 'O Thaiz" ;)
