No. The U.S. State Department regulations prohibit all J-1 trainee and Interns from accepting employment in the U.S. outside your training or internship assignment. It is very important that you evaluate your program expenses before applying for the program as you will be required to show proof of funds needed to sustain your living expenses while in the U.S. Any unauthorized employment will subject you to immediate termination from the J-1 visa program and you may also face deportation and/or other penalties from the U.S. government.
