Internships allow students who have yet to graduate gain experience in positions related to their major or future career by working in companies. Some universities recognize internships as part of the educational curriculum and give academic credit for it. Please inquire directly with your school about the availability of internship programs at the school and the possibility of earning course credit.
If the internship comes with an income, you need to obtain "permission to engage in activity other than that permitted under the status of residence previously granted." If you wish to do an internship that will require you to work more than 28 hours per week, please apply for "permission to engage in activities other than that permitted under the status of residence previously granted." This requires you to submit materials that make clear the nature of the internship to a regional immigration services bureau.
