Introduction
The purpose of this requirement is to ensure that the home country benefits from the exchange visitor's experience in the United States. The two year requirement states that the person who is subject to the two year home residence requirement may not change to another nonimmigrant status in the US or acquire H, L, or immigrant status, until that person has resided for two years in his/her home country or country of legal permanent residence or has requested and been granted a waiver of the two-year requirement.
Please note that not all exchange visitors are subject to this requirement.

Applying for a Waiver

Exceptional Hardship: Applicant would apply for a waiver based on exceptional hardship to their US citizen or lawful resident spouses or minor children.
Persecution: Applicant would apply for a waiver based on their belief that they will be subject to persecution because of race, religion, or political opinions if they returned to their home country.
Interested US Government Agency: A US government agency may apply to DOS for a waiver in behalf of the applicant if they are interested in the applicant's programs or projects and if they believe that it is in the best interest of the United States to allow the individual to remain.
No Objection by Home Country: The applicant applies for a waiver based on a statement from their home country that there is no objection to a waiver of the two year home residency.
The Waiver Application Process
