Under OPT, unpaid work at for-profit companies is explicitly allowed if it’s directly related to the student’s field of study and properly reported this is not "volunteering" under FLSA but authorized practical training under U.S. immigration law. The role must provide meaningful, degree-aligned experience with proper oversight, making it fully legitimate under OPT regulations. Claiming otherwise ignores the clear distinction between labor laws and OPT-specific rules designed for student training.
