Hi and welcome to the forum.

The first place to check is the website for the US Embassy in Ottawa AMCITS • Canadians who require U.S. visas to determine if you will need a visa or not and how to get the proper visa for the type of work you are planning on doing.

Do you have a job lined up? Or do you have the qualifications for a specific type of job? Those are probably the two critical questions. Give a shout as more questions come up.
Cheers,
Bev
