The Exchange Visitor Skills List (J Visas) is a list of fields of specialised knowledge and skills that are deemed necessary for the development of an exchange visitor's home country. When you agree to participate in an Exchange Visitor Program, if your skill is on your country's Skills List you are subject to the two-year foreign residence (home-country physical presence) requirement, which requires you to return to your home country for two years at the end of your exchange visitor program, under U. S. law. Review the Exchange Visitor webpage to learn more.
