What you said about Canada is 100% correct.

Peanuts for a pay + add miserable winter weather.

That said Canadian passport is high quality and so far TN-to-Green card is ~2yrs process. Took me 1.5 yrs.

Better than US passport in some aspects - especially that US passport is essentially a way for IRS to keep you tax hostage no matter where you are.

Can't say about Germany - likely will be some good comments here

What is the path from TN to green card? Everything I've read is it's impossible unless you get an H during your TN.

Just FYI, I believe TN to GC will be quite lengthy for OP since his place of birth determines the GC quota

[Trias11]

Correct, thats important. Might be quite different from my experience

...or the place of birth of OP's spouse.
