Possible job offer for me - my spouse wants to work too.

You speak from personal experiences?

I have yet to hear from a Canadian who was unsuccessful in applying for GC, whether they started it from TN or H1. Agreed that I don't know many of them, but it is still 3 from TN-GC and 2 TN-H1B-GC

Applying for H1B is a pain and Canadians don't need to apply for longer term when they can get a TN so easily.

However, if your TDs can't do anything except breathing the so more marvelous and refreshing air of the US and bathe in it's so better freedom, then I understand why someone would like to fill for GC. I am.

(I used some sarcasms by the way. )
