I got this but still at end it say check it "Most commonly, students want to know if they can start their own businesses while on OPT. The SEVP explained that it is possible to be self-employed, as long as the nature of the business relates to the student's degree program and the student is actively engaged in this business. If self-employed, the student must work full time. While not specifically stated, this is likely to be an area in which the documentation of employment and the nature of the activities could be reviewed closely. So consider the risks and discuss the possibilities with your immigration counsel."
