I am currently doing part-time masters program while working full-time with an employer who is sponsoring my greencard application. I am planning to do part-time internship during one day of the week at off-business hours and during weekends. I am planning to do the part-time internship while still working full-time with my current employer. What are the risks involved? Do I need to get permission from my employer? Do I need to submit any information to USCIS? Will I face any issues related to my pending I-485 application?
