Canadian citizen applying for TN Visa
I received an offer to join a US bank as an analyst () and will need a TN to get through the border. I have a bachelor's degree in mathematics (major is math/business administration), so naturally I believe that I should be applying through the Mathematician occupation as the job letter can be reworded to explain my responsibilities specifically touching on things like data analysis to support business decisions, interpreting data/reporting conclusions drawn from mathematical analysis, deciding what data is needed to answer specific questions, etc. The employer's law firm wants to apply through the accountant or economist route, although I have a B.Math. I genuinely feel more confident going down the mathematician route because that's where my degree is in, and I can definitely see a scenario where the border agent says B.Math degree is not the correct educational background for an economist role.
I am aware that post-2017, there have been changes to economist to prevent financial analysts coming in through that occupation, so I think my mathematics bachelor degree gives me a unique advantage.
Really concerned about this and looking for thoughts!
