Transfer of program

An exchange visitor who transfers from one program sponsor to another cannot use that transfer to prolong his or her stay in the United States beyond the limitations of the pertinent category, but he or she will be subject to the time limitations for the specific category. An exchange visitor must have special permission from USIA to change from one category to another and may not do so if it is apparent that the reason for the attempted change of category is principally to delay departure from the United States. An exchange visitor in any category may transfer from one program sponsor to another if the purpose of the transfer is to complete the objective for which he or she was admitted - and if the exchange visitor remains within the same category.

Termination of program

• Fails to pursue the activities which he or she was admitted to the United States.

• Is unable to continue unless otherwise exempted pursuant to these regulations.

• Violates the Exchange Visitor Program regulations and/or the sponsor's rules governing the program if, in the sponsor's opinion, termination is warranted.

• Willfully fails to maintain the insurance coverage required under the Exchange Visitor regulations.

• Engages in unauthorized employment, it is the responsibility of USIA, not the sponsor or responsible officer, to determine when unauthorized work has occurred and to terminate the exchange visitor's program.

Upon termination from a program the individual has 30 days from the effective date of termination to depart the United States and surrender Form I-94 confirming departure. The individual is considered to be in status during that 30-day period.

Twelve months bar for professors and research scholars

Professors and research scholars who have been physically present in the Untied States in J status for all or part of the 12 month period immediately preceding the date of program commencement set forth on his/her Form DS-2019 is subject to the 12 month bar. The professor or research scholar must be absent from the U.S. for a period of 12 months before participating in another J-1 program.

Two years home country physical presence requirement

The 2-year home country physical presence requirement is one of the most important special characteristics of J-1 status and should be thoroughly understood by the exchange visitor. The determination as to whether an exchange visitor is subject to the 2-year home country physical presence requirement by virtue of the need for his or her specialized knowledge or skills in the home country is made by reference to the Exchange Visitor Skills List, an official list of fields of specialized knowledge and skills needed in each country, as determined by the governments of those countries.

The exchange visitor is subject to the 2-year home country physical presence requirement only if participation in an exchange program began after his or her field of study appeared on the skills list. The 2-year home country physical presence requirement may be waived for any one of four reasons. The Office of International Programs has handouts on procedures for the waiver application.
