If you want an answer you are going to have to type more than two words. It's a sign of laziness.

Sorry I Though that I include all the details.

I have a TN visa and my wife is a non resident alien (Canadian).
Since when I join my company all my papers have been as "married" (W4, etc). So I am not sure how should I do my taxes since my wife doesn't have a SSN or ITIN number.
Should we apply for the ITIN number before submitting the taxes or what should I do.

Thnak you
