Some interesting NAFTA TN Visa facts that may help you:
TN Renewal Tip
The TN can be renewed quickly at a port-of-entry or by mailing an application to the Vermont Service Center.
TN & Immigrant Intent Tip
Unlike the H1b visa or L-1 visa, the TN status does NOT allow for immigrant intent. This means that when you are applying for the TN or seeking to enter the United States in the TN status, you cannot have the intent to immigrate to the United States and remain permanently. However, there are certain ways to navigate this aspect of the TN. It is highly important for you understand this concept and discuss the matter in detail with your TN attorney as it can arise when seeking a green card through employment or through the marriage green card process.
Change of status to TN
If you are already in the United States in another valid nonimmigrant status, such as the H-1B, L-1, O-1, or F-1, you can apply in the United States to change your status to the TN status through a change of status application with the Vermont Service Center. You can also just go to a port-of-entry and apply for a TN.
TN Border Tip
Know your border! It is highly crucial to the success of any TN application for you to have indepth knowledge of the protocol and trends at the borders you’re considering for application. Each border tends to have its own personality and they each approach the TN process in a different manner. Inside knowledge of this information can be crucial for the success of any application.
TN authorized stay Tip
You are only authorized to stay and work in the United States in the TN status as per the period of authorized stay indicated on your I-94. Technically speaking, there is no grace period in the TN status. What this means is that if your authorized stay period expires or you are terminated from your job, you must leave the United States immediately.
TN forms Tip
If you are applying for a TN at a port of entry, there are no required USCIS forms that need to be submitted. If you are applying for a new TN or an extension through the Vermont Service Center then you will be required to submit Form I-129 with your application.
