Two groups of family-based immigrant visa categories, immediate relatives and family preference, are provided under the provisions of U.S. immigration law, specifically the Immigration and Nationality Act (INA). You may wish to review our Directory of Visa Categories on usvisas.state.gov to learn more about these two categories of immigrant visas, as well as other types of immigrant visas to the United States, including our Diversity Visa Program.
To apply for an immediate relative or family preference immigrant visa, follow the steps on the Immigrant Visa Process on usvisas.state.gov. Once you have completed those steps, review the instructions given to you by the National Visa Center (NVC), along with the information presented on this website, for further guidance and instructions. U.S. citizens residing in Greece may file petitions at the USCIS Athens Field Office.
