Form G-325A is used to provide biographical information to support new or existing petitions filed by immigrants to the United States, explains American Immigration Center. The form asks for information on family, work history and past residences to help the U.S. Department of Immigration make a decision on a case.
The G-325A form can be used to supplement a green card application or provide the information needed for a background check during a status change, states Nolo. Applicants should only complete the form when instructed to do so on another application for immigration, according to the Department of Homeland Security. The form is two pages long, and there is no filing fee.
