Some questions about TN Visa

To enter under the category of Mathematican, would a bachelor's degree in physics be considered a related field? I am a theoretical physicist. For all intents and purposes, I am a mathematican.

So essentially the job offer letter needs to say that. I would be astonished if they turned you down with those qualifications. But then I've seen them do all kinds of dotty things.

To answer your other question, you can have umpteen employers on TN-1 if you want them. TN-1 was originally designed to make life easier for people who are essentially cross-border workers. So say you're a consulting MD for example, you could be a consultant to who knows how many hospitals, while working for a hospital in Canada as well if you want.

The same applies if you are a mathematician working for various banks. It just gets to be a pain going to the POE to add on another employer. You can do it using the I-129 application as well, but that thing makes my head spin (and it costs more). There are some threads on here where people have done it.

I agree with Steven, the applicant has outstanding credentials. However, I would not "snow" anyone in a public forum.

I remember a story about 9 months ago about some degreed Electrical Engineers applying at Buffalo as Computer Systems Analysts. They were denied entry and the CBP said: "No you are not Computer Systems Analysts with an Electrical Engineering degree." Again, the application of case law definitely played a role in adjudication.

So yes you could possibly be denied as a Mathematician attempting to enter with a Physics degree at the New York crossings.

I was only trying to point out the inherent dangers with your application.

I really appreciate you pointing out the dangers. My own experiences bears out what you say. Thus far, I have had to apply for a TN Visa twice, once at the Ontario/New York border and another time at the Quebec/New York border. The border offical at the latter gave me a much easier time.

I will consulate a lawyer and avoid the Ontario/New York border crossing.
