USCIS processes all the applications, petitions, or benefits requests filed with them at their offices called as USCIS Service Centers. Each of the Service centers is identified by a 3 digit code.

What are USCIS Service Centers ? How many ?

USCIS Service centers officially fall under Service Center Operations Directorate(SCOPS). There are five service centers under SCOPS. They primarily process the applications and petitions related to US immigration. They do not provide any in-person services such as walk-in appointments, clarifying questions in-person, or conduct immigration related interviews.

USCIS service centers process applications or petitions that are filed online, mailed to the service centers directly or filed with a USCIS Lockbox. Below are the list of five service centers

Vermont Service Center
California Service Center
Potomac Service Center
Nebraska Service Center
Texas Service Center

National Benefits Center is not a USCIS service centre, but you would see that code in USCIS Receipt Number.

There are many USCIS service centres across America. Each of the USCIS service centers processes applications or benefits that satisfy a certain criterion. For instance, some of them process only applications filed from certain states, while some of them process only certain types of applications. The idea to have multiple service centers across US is to make sure the USCIS workloads are balanced. Also, the USCIS workload is transferred between service centers as needed to balance load.
