>a) Engineering is covered by TN visas, but you have to have an actual engineering degree. Claim you're a software engineer and they have every right to deny the CS grad.

Not true at all. BSc in Computer Science is perfectly fine for Software Engineering jobs.

Look up NAFTA Appendix 1603.D.1

> b) Programming is not covered. This is simple fact of NAFTA. It's a process where applicants are told to be super careful with the wording (sort of like saying you're "going to meetings" when crossing the border for work related things), and at most the actual allowance is for a software analyst that does a small amount of programming.

That's true. But seriously is there anyone hiring "computer programmer" these days?

>>And once you have a TN visa, that is zero guarantee -- any single border guard can reject it, at any time.

True. Remember to carry all your paperwork with you whenever you cross the boarder.
