did u try at tutoring center or sth like tht in ur college. if u maintain a good GPA and can tutor, u can start frm there.. otherwise, apply for a work permit. once u have a WP, then get a job and then apply for SSN thru tht job.otherwise, seek a paid internship.. n apply for ssn. the basic thing is tht ss office look for a legitimate source of taxable income. best of luck
