Is there an age limit for dependents attending college on the TD visa?

Dependents on a TD visa must be under 21 years old to maintain status; after that, switching to a student visa may be necessary to continue college studies in the US.

It is important to understand that the United States immigration system has well-defined rules for dependents of TN visa holders, especially concerning age and length of stay in the country. In the case of dependents who accompany TN visa holders-who, in the context of the derivative visa, are designated as TD-there are some aspects to consider when it comes to attending college.

In general, there is no age limitation to enroll in a higher education institution in the United States. That is, the educational regulations themselves do not impose an age ceiling for entering a college course. However, for a child to qualify as a dependent under TD status, immigration law typically requires the child to be considered a dependent of the TN visa holder, which in most cases means being under 21 years old.

Thus, if the dependent exceeds this age limit, they will automatically no longer qualify for TD status, even if they are already attending or intend to enroll in college. It is worth noting that when the dependent reaches the age limit, it may be necessary to seek a status change-for example, transitioning to a student visa (F-1)-if the desire is to remain in the country and continue their studies.

It is crucial that all status changes comply with United States immigration laws to avoid future complications. Always remember to seek updated information and, if necessary, consult experts in the immigration field, avoiding miracle promises or marketing campaigns that guarantee results without legal backing. Staying informed and following official guidance is the first step for a smooth and secure journey in the country.
