The U nonimmigrant status, often referred to as the “U Visa,” is a form of immigration relief available to noncitizens who have been victims of serious crimes in the United States. As part of the protection given to victims of crimes, U petitioners are able to include certain family members in the application process. These family members are known as “derivatives”. For many family members, being a derivative on an application may be the only way they will be able to get legal status in the United States. This practice advisory outlines the requirements for U nonimmigrant derivatives as well as considerations to keep in mind when filing an application.
