The TN visa is an important tool for professionals from Canada and Mexico who wish to perform activities under the auspices of NAFTA (or currently USMCA) in the United States. In this context, it is essential to understand how service at the border works, especially when dealing with the procedures of U.S. Customs and Border Protection (CBP).

Generally, the entry points operated by CBP operate 24 hours a day, which means that, technically, the option to present your documentation for the TN visa is available at any time. However, it is important to remember that passenger flow, the availability of specific services (such as detailed interviews or additional assistance), and the internal organization of some border points may vary. Therefore, it is advisable to check the exact operating hours of the specific port where you will make your application in advance, either through the official CBP website or through updated information provided by local border authorities.

I also emphasize the importance of carefully following all U.S. immigration rules and regulations, seeking information directly from official sources. This practice avoids misunderstandings and ensures that your processes follow the correct and legal path. In addition, exercise extra caution with unfounded miraculous offers or misleading promises that arise in marketing campaigns; remember that the immigration process is serious and requires strict compliance with existing laws.

If there are specific doubts or information that need to be updated, consult the official CBP channels or seek guidance from qualified immigration professionals to confirm that all steps are in accordance with the necessary legal procedures.
