Hi,
I am about to apply for a TN visa but I want to be sure to have everything in order before going. the requirements list that I find around the web is somehow not that clear.
1. do you need all original documents or photocopies are ok?
2. 3 years of experience requirement - how do you prove this experience? - tax forms? simple letter from previous employer?
3. if I have an offer from an employer for a short period (1-3 months), with possibility of extension. do i need go back to canada after 3 months? or the TN is good for 12 months and I can stay as long as its not expired?
4.how do you know your school (diploma) is certified? ( i attended a private school and been told told that my diploma may not be valid)
