The bottom line - If you plan to move to the US for 3 years it is worth to have your entire TN packet reviewed with a legal professional .

I hear about all these one sided \"horror\" stories of how people have been (mis)treated at the border during a TN Visa interview. I have a friend with an MBA and 15 + years experience in Sales & marketing. Since there are no job titles under the NAFTA relating to Sales and marketing, the only thing was nearest was a \"Management consultant\" category.

In my friend's case, he has decided not to go on a TN visa, even though an attorney in Vancouver told him that he would prepare the papers in a professional manner, to make sure there was no hitch in the interview process.

Despite this, my friend has decided not to go on the convoluted route. Instead he will to go to the US on his green card, which has been approved.

The interview process is very thorough. Simply because the applicant is from Canada, does not make the process any simpler . The visa officer is left with the job of making sure that the education, work experience and skill sets have a direct co-relation to the work that will be undertaken in the US.

If you want to go to the US on a TN visa, it is worth spending a couple of thousand bucks on an attorney. That is a small price to pay, compared to the agony of rejection.
