In 2019, over 3,400 green card recipients lived in Rhode Island (Statista). The dept. of homeland security’s citizenship and immigration department (USCIS) processes these and other cases at their field offices. Field offices are present in all parts of the country. To categorize these physical locations, the federal agency uses a system consisting of Districts instead of States or Cities. There are a total of 26 districts and some districts have jurisdiction over counties in multiple states.
Regardless of the location of the office, one of the duties it performs is interviewing immigration hopefuls, except those seeking asylum. The government has separate centers for asylum seekers. There are different ways in which you can find a field office. Of course, you can search them using your favorite search engine or the website that lists locations. However, for the most up-to-date information, it’s better to use the office locator tool provided by the USCIS. After you enter your zip code, this search engine gives you the name and address of the nearest office.
