The Q nonimmigrant exchange program is for the purpose of providing practical training and employment, and to share the history, culture, and traditions of your home country with the United States.
There are two nonimmigrant visa categories for persons who want to participate in Exchange Visitor programs in the United States. The J nonimmigrant visa is for educational and cultural exchange programs designated by the Department of State, Bureau of Consular Affairs. The Q nonimmigrant visa is for international cultural exchange programs designated by USCIS.
Only employers who administer cultural exchange programs are allowed to petition for Q nonimmigrants. The purpose of the Q nonimmigrant visa is to facilitate the sharing of international cultures. It is an employment oriented program, but an integral part of your duties must have a cultural element. You must be at least 18 years old and be able to communicate effectively about the cultural attributes of your country.
