What is LUD?

LUD is the "Last Updated Date" registered on a particular case that is registered by the applicant/petitioner in the USCIS Case Status System.

Types of LUD

  1. Soft LUD : This is a LUD change in the online system that is NOT accompanied with an email to the applicant/petitioner.
  2. Hard LUD : This is a LUD change in the online system that is accompanied with an email to the applicant/petitioner.

What triggers an LUD change?

  1. USCIS software batch jobs
  2. USCIS officers/adjudicators processing/viewing/adjudicating a particular case

Remarks on the significance of LUD

LUD changes can occur frequently due to USCIS software system batch jobs. So it is never certain what a particular LUD change means.


1. What is a Soft LUD?

It refers to a change in the "Last Updated" date you see on your USCIS portfolio page WITHOUT an actual change in the status of your case. For example, you log into your CRIS account at and notice that the date listed under the "Last Updated" column on your case has changed to today's date, but the status is still "Application Received and Pending".

2. What is "CRIS" and "portfolio page"?

You can create your own "account" page on to register your pending case(s) with USCIS so that you automatically receive an email whenever the status changes on your case.

3. What does the occurrence of a 'soft LUD' mean?

As the USCIS portfolio page itself states, it simply means that there was internal processing done on your case. This can be as simple as shifting your file to another shelf where it will wait for another few months or years, or could mean that your file was looked into for purposes of casual checking, or that your file is being adjudicated.

4. How do I know if the 'soft LUD' on my case is an indication that my case is being actively adjudicated or not?

There is ABSOLUTELY NO WAY to know what the 'soft LUD' means unless and until there is an actual change of status on your case (e.g. your status goes from "pending" to "approved).

5. I'm seeing a series of daily 'soft LUDs' on my case for the last few days. Should I get excited?

A series of 'soft LUDs' might or might NOT mean that a decision on your case is imminent. 'soft LUDs' are random and can occur on anybody's case or not at all.

6. I saw a 'soft LUD' on a weekend. Does USCIS work on weekends?

No, USCIS does not work on weekends Generally, a 'soft LUD' on a Saturday or Sunday is just a system updating to reflect internal processing that may have happened on Friday. Many people have actually gotten approval emails on Saturday (or sometimes Sunday) stating that the case was approved on Friday! It is perfectly normal for a computerized update to occur a day or two after the actual processing occurred.

7. Will I necessarily see a 'soft LUD' on my case before a decision?

No, not necessarily. Some cases can show 'soft LUDs' in the days leading up to a decision, but other case statuses can change without ever having seen a 'soft LUD'.

8. Is there any situation where I should expect to see a 'soft LUD'?

There are at least three situations where one would NORMALLY expect to see a so-called 'soft LUD'. These are: A- In the day(s) immediately following the receipt of the application or petition by USCIS. B- After your FIRST biometrics appointment (Code 3) - but NOT necessarily after any other biometrics appointment - only your first. C- After you change your address with USCIS (NOT AR-11, but actually change your address with USCIS for each of your pending applications).

9. I thought AR-11 is what you use to change your address.

Filing AR-11 and changing your address for your USCIS applications are two separate things. Filing AR-11 is required by law for every alien (including permanent residents) within 10 days of moving. However, AR-11 is for a separate department at the Department of Homeland Security; it will NOT inform USCIS of your new address for applications you still have pending. For that, you will have to update USCIS separately.

    • The online address change link on will guide you through both sets of address changes, first the AR-11 form, and then once completed, for USCIS pending applications. But paper-filing AR-11 by itself will not update USCIS with your new address and will not generate a 'soft LUD'. **

10. I am seeing 'soft LUDs' on my case even though it was just approved. What's going on?

Yes, it is normal (but not always the case) to see 'soft LUDs' after a case is approved. After all, the case still has to be processed as 'approved', archived, and filed away, doesn't it?

11. I replied to an RFE recently but haven't seen a 'soft LUD'. What does that mean?

It probably means nothing. Usually you should see an actual case change to inform you that the 'Request for Additional Evidence Received, Case Processing Resumed', but this doesn't always happen. Your case has probably resumed processing though.

12. I did see my case status change to reflect that they received my RFE response, but I am still seeing 'soft LUDs' since that day. Why?

If they receive your RFE response and are processing (or filing away or transferring) your file, you will invariably see a 'soft LUD'.

13. Wait - but I didn't see any 'soft LUD' after my 'RFE received' status change!

Again, the occurrence of a 'soft LUD' is random, and its presence or absence does not indicate anything by itself. Two files can be processed together on the same day, and one will show a 'soft LUD' and the other will not - this happens all the time, and it is nothing to be concerned about.
