The citizenship and immigration department (USCIS) of the Department of Homeland Security (DHS) was formed 18 years ago. The federal agency is the main government body processing cases of non-asylum-seeking immigrants. It operates through offices and application centers spread across the States and territories. Besides physical locations, there’s also a phone service and a website that covers different immigration topics and case processing, along with offering a virtual assistant bot to information seekers.
A field office is a location where USCIS representatives interview immigration hopefuls. It’s also the venue for citizenship ceremonies. The agency divides its offices into Regions. There are the Central, Western, Northeast, and Southeast regions. Within each region, there are multiple Districts and within each district, there are the field offices.
