What does a USCIS Receipt Number (MSC, LIN, SRC, EAC, WAC, IOE) Mean?

[Leer Publicación en español]   [Ler Post em Português]

A USCIS Receipt Number is very similar to tracking a package on Amazon. The Receipt Number, better called a tracking number, allows a recipient to track a filing online, over the phone, or in person at an INFOPASS.

Now, let’s dive deeper!!! The Receipt Number can be broken into four parts. See the diagram below:

USCIS Office Locations have the following 3-digit codes:

  • MSC – National Benefits Center;
  • NBC – National Benefits Center;
  • EAC – Vermont Service Center (formerly known as Eastern Adjudication Center);
  • VSC – Vermont Service Center;
  • WAC – California Service Center (formerly known as Western Adjudication Center);
  • CSC – California Service Center;
  • LIN – Nebraska Service Center;
  • NSC – Nebraska Service Center;
  • SRC – Texas Service Center (formerly known as Southern Regional Center);
  • TSC – Texas Service Center;
  • IOE – ELIS (e-Filing); and
  • YSC – Potomac Service Center.

Fiscal Year

The Receipt Number follows the Fiscal year, and not the Calendar year. The Fiscal year starts October 1st and ends September 30th. So, for example, if a filing is “received” on October 1, 2018, the “year” will actually be 19, since you will technically be in the fiscal year 2019.

Day and processing number

The # of days and the # of filings performed on that day make up the last 2 parts of a USCIS Tracking Number. Usually, when you file forms together, you will see consecutive numbers, and that is in part due to the officer receiving all of the receipt numbers at the same time on the date of receipt.

My IOE number is different from above

IOE or ELIS filings are governed by a different “setup” for receipt tracking numbers. Filings like the I-90, N-400, I-821D, and OS-155A are provided a more extensive syncing to the USCIS My Case Status Online System. If you haven’t attempted to view the status of the filing online, it is highly beneficial.

Frequently, IOE filings are provided an Online Portal with USCIS. If you receive an Access Code Notice, it is wise to create the account as USCIS immediately.

Why does my Case Number start with MCT?

MCT is a code associated with I-539 Change/Extension of Status. The service center associated with the filing can be found at the bottom left side of the USCIS Receipt Notice.

My Online USCIS Case Status never updates?

This is a common question that most of my staff get asked. Usually, the online status stays on “filing received.” The Online Status is a courtesy feature that isn’t always updated by USCIS. Just because a filings status isn’t moving, that doesn’t mean USCIS isn’t going to schedule a biometric appointment or actively review a file. The filing continues to process even when the Online Status never updates.
