When a citizen of another foreign country wants to enter the US, he must have a proper visa which can be a nonimmigrant visa for temporary stay or an immigrant visa for permanent residency. The US has created an agreement called as The North American Free Trade Agreement (NAFTA) to provide economic as well as trade relationships between the US and Canada, Mexico. This visa was called as TN visa for nonimmigrant NAFTA Professionals which allows the citizens of Canada and Mexico to work on tn visa jobs in USA or carry on prearranged business activities. Since Canadians often gain better entry in the US with greater ease then it’s because of this NAFTA agreement which has many treaty provisions within.
Since among all NAFTA-related visas the most useful among all was the TN-1 visa which was modeled like the H-1B and was given to Mexicans as well as Canadians to gain tn jobs in US. The TN visa has the following advantages over traditional H-1Bs and the basic requirements are:
TN visa is granted only for one specific employer and if needed for more than one employer then multiple TN-1 applications can be made. Most of the self-employed professionals will not come under this category and must consider to be on the E-2 Treaty investor category. It is possible that you can apply for TN-1 visa with quite minimal documentation but holding all the valid documents such as the description of the position from the US employer like temporary or permanent, copy of employment contract, duration, salary and also how is the nature of the employer’s business etc., qualification of the candidates with proofs, candidate CV, passport originals and visa stamps plus I-94’s, social security number of the candidate, foreign address and local address etc.
Once the TN status is given then it is valid for 3 years and only for a specific employer if requested originally. Changing the employer that is for a TN visa change jobs then you will be needing to start from the scratch where can apply with a new application. If you seek employment with only one single employer for more than the given time period of 3 years, then it can also be renewed for an indefinite period.
Now coming to the renewal process, the renewal is accomplished through a mail within the US or by returning to the border and by presenting a new application. However, the TN visa can be renewed after every 3 years but it is not a permanent visa and may even deny further renewals if the visa is misused and used as a green card. Also, the occupations that can petition are quite limited than for an H-1B visa. Most of the Canadians have successfully renewed their TN visa status for more than a decade but there a few others who have been denied to renew after 3 or 4 years. Mexicans also faced such issues when it came to renewals.
The main task for you here is to make a good career in the US and since there are many opportunities for Canadians and Mexicans to be employed in the US on tn visa. It will be a truly good experience for you all to live, work and experience the open culture and do a job in a diverse environment. You can also search for jobs in USA for Canadian citizens as well as for Mexican citizens here and all you need to do is register and submit your requirements.
