Hi my wife is a F2 visa holder at Virginia Tech. She wants to work in a research lab at VTech on a volunteer basis. She WILL NOT take any MONEY or WILL NOT USE THE TIME SPENT IN LAB FOR CREDIT HOURS FOR A DEGREE. However she would like to use the time spent in lab as experience when she applies for her graduate study. The research lab rejected her saying that she can only work in charitable organization like YMCA. My question is that Is she within her legal status to work as a volunteer in a research lab specially if she is not taking any money or using the time as credit hours. Why is the lab rejecting her? Do they have any legal ground to reject her.
Please help me if you can.
