To view the status of a case, please enter the corresponding application
receipt number. The 13-character application receipt number can be found on
application notices you have received from the USCIS. It begins with three
letters such as (EAC, WAC, LIN, or SRC). Dashes ("-") should be omitted
when entering a receipt number. However, all other characters, including
asterisks ("*"), can be included if listed on your notice as part of the
receipt number.
Listed above are the possible steps an application or petition may go
through during processing. Not every application or petition will spend time
in each of these steps. Once you enter your receipt number you will see the
steps that will always be required for that particular application or
petition. The step in the process where your case is currently located will
be highlighted. Other steps will appear if your case requires that
particular step.
