I copy some related information here from the website:

Two-Year Foreign Residency Requirement and Waiver (INA 212e)

Exceptional Hardship Waiver

This applies to a U.S. citizen (or permanent resident) spouse or child of an exchange visitor. If the exchange visitor can demonstrate that his or her departure from the United States would cause extreme hardship to his or her United States citizen or lawful permanent resident spouse or child, he or she may apply for a waiver. (Please note that separation from family is not considered to be sufficient to establish exceptional hardship.)
