Can I Apply for a Green Card While Under TN Visa Status?
Like most temporary/nonimmigrant visa classifications, the TN visa has a temporary entry requirement.
But applying for green card may be possible while under TN visa status.
Careful planning is required to ensure continued work authorization, mitigate travel issues, and avoid jeopardizing status.
See, e.g. TN & Adjustment of Status (AOS) Processing.
