When you submit an immigration application with the U.S. Citizenship and Immigration Services (USCIS), you are assigned a receipt number. This receipt is 13 digits long and is a mix of numbers and letters. It is unique to you and your specific application. You can find it in the upper left-hand corner of your Form I-797.
The first three letters of your receipt can tell you precisely where your application is being processed. There are only four different processing centers in the U.S. The following locations are listed with their specific three letter code:
EAC - Vermont Service Center
WAC - California Service Center
LIN - Nebraska Service Center
SRC - Texas Service Center
There are three ways to check the case status of your visa application.
The simplest way is to go to the USCIS "My Case Status" webpage. Once you arrive, you'll see a white box directly underneath some text that says "Enter your receipt number." Type your receipt number there, hit the "Check Status" button beneath the text box,and you'll be able to see the status of your application.
You can also call 1-800-375-5283 to check your status. If you call between Monday and Friday anytime from 8:00am to 6:00pm, you will receive live assistance. However, calling outside this window will mean you will not be speaking to a human. Instead, after following the stated instructions, you'll hear a voice recording tell you the date that you filed your application and approximately how long it should take until it's approved. This number can also have long wait times, so be prepared to stay on the line for a while.
If you are outside of the U.S., you must call 785-330-1048 to check the status of your case. Please note that there is not live assistance available through this number.
Find out which service center your application is being processed at by referring to the list above. You must send an email to that location to inquire about the status of your application. The corresponding email addresses for each service location are:
Vermont Service Center (EAC) - email@example.com
Vermont Service Center (EAC) - firstname.lastname@example.org
Vermont Service Center (EAC) - email@example.com
Vermont Service Center (EAC) - firstname.lastname@example.org
If you do not receive a response within 21 days of emailing a service center, you may contact the USCIS Headquarters Office of Service Center Operations directly by email at SCOPSSCATA@dhs.gov.
