Over 8,500 people who obtained legal permanent residence were living in Oregon in 2019 (Statista). The U.S. Citizenship and Immigration Services (USCIS) has the responsibility of handling immigration-related applications except for those that are asylum applications. The federal agency fulfills these responsibilities through its physical locations and other services, including an official website and a contact center.
The USCIS offices are spread all over the U.S. and territories. International applicants are encouraged to submit their applications at an office located in their country. The whole U.S. is divided into four regions, namely the Northeast, Southeast, Western, and Central. Within each region, there are multiple Districts, and in each District, there are multiple field offices.
The main duties of a field office include taking interviews of applicants, meeting applicants for case-specific matters, arranging citizenship ceremonies, and providing information that supports that’s available online. The USCIS provides various resources through its official website including, “How Do I” guides, what to do before/after applying, and tools to keep track of applications.
