I have a T-visa. Can I work legally in the US?
Yes, if you are granted a T-visa, you are automatically granted an employment authorization document (EAD). You do not need to fill out separate paperwork to get employment authorization - your T-visa application also acts as an application for employment authorization.
Note: If you are applying for derivative T-visa status (T-visa status for your immediate family members), you must apply for employment authorization for them separately by filling out Form I-765.
