I already have an SSN from when I studied in the USA. Can I use the same one?

The Social Security Number (SSN) issued by the USA is valid for life, meaning that if you already received one during the time you studied in the country, it remains your personal number. However, there are some important points to consider when it comes to using this number during a status change, such as obtaining a TN visa for work.

Generally, your SSN stays the same regardless of immigration status. If your card had the notation “VALID FOR WORK ONLY WITH DHS AUTHORIZATION,” it means that although you have an SSN, it can only be used for paid activities if there is a valid work authorization issued by the Department of Homeland Security (DHS).

In the case of the TN visa, a valid work authorization is an integral part of the visa, which usually allows the use of the previous SSN for employment purposes. Still, it is very important that you keep your information updated with the Social Security Administration (SSA).

In some situations, it may be necessary to present the new work authorization so that the SSA records can be updated or so the employer can verify the SSN eligibility.

If you have doubts, it is recommended to contact the SSA directly or seek guidance from immigration professionals carefully and informedly. Always remember the importance of strictly obeying United States immigration laws.

Seek reliable sources and avoid promises of guaranteed results, especially those promoted by marketing campaigns that may not provide correct or updated information. This caution is essential to maintain compliance with regulations and avoid future complications.

I hope this explanation has clarified your question. Each situation may have its particularities; therefore, staying well informed and seeking confirmations with the competent authorities is always a prudent attitude.
