The J-1 visa allows students to visit the United States as exchange visitors to perform a specific internship at the end of which, he/she must return to his/her home country. For employers, it is important to ask the J-1 holder whether he/she is subject to the two-year foreign residence requirement, pursuant to which, the J-1 holder must depart the United States and reside in his/her home country for two years prior to coming back to the United States. In very rare circumstances, the two-year requirement may be waived.
