A student must prove the availability of adequate funding for the complete period of study without the necessity to earn money from U.S. employment. However, students may seek limited employment in certain circumstances during and after their period of study. This employment may be on-campus. However, if it is off-campus, it must usually be related to their course of study. Except in special circumstances, such as for certain Asian students whose home country currency has been devalued, it cannot be to supplement the financing of their school and living expenses.
Students generally enter in one of three temporary educational classifications.
Responsibility is moving to the Department of State not later than October 1, 1999. If funding comes from the student's home country or the United States, there is usually a requirement that the student return home after graduation and practice the newly-acquired skills for two years. This requirement applies especially to medical students. Unless the applicant is an exceptional or internationally-acclaimed professor, it is likely that either temporary or permanent entry will require the prior approval of the Department of Labor before INS and State Department processing may be started. A college or university teacher or professor entering temporarily will be processed in the H-1B classification.
