Hi

First of all I am really sorry you are out of status, It is not easy trying to get a degree and also working to pay for it. But Congratulation for achieving what you came to America for.

First of all,

1. Canadian official don't care if you are out of status as long as you were admitted in to USA as legal and you were in status for over a year.

and Second of all

2. if you are trying to apply for skilled worker you need 10 years work experience and you need to provide w-2 to tax returned to prove that.

Good luck
