Science degree from a US university you mean? I'm not trolling, genuine question.

Canadian university degree is fine. Look up TN 1 visa if you want more details.

Any university degree is fine but if it's not from a NAFTA country it needs a Foreign Equivalency Certification.

But from non-nafta it's not TN, right? What's the approach there? Skilled something?

No you can get a TN with it. I used my British degree.

Edit: You still need to be a Mexican or Canadian citizen.

Thank you!

No problem https://www.wes.org can certify your degree.
