There're two or three options:
1) Fastest:
Prerequisite: you need to know your employer phone number filed with your application
Call 404-562-2131, then press 1, then press 2
But since AVM is updated rarely, your case might not be put in the system for a long time.
2) Send a fax to DOL to ask for the case number.
Information need to put in the fax:
a. Alien name
b. Employer name
c. State
d: forward date
Fax number: 404-562-2152
This way gonna be slow, but you can trust the information you get from this source.
I sent my inquiry on 03/04/04, and got the response on 04/19/04 when I almost forgot about the fax.
3) If you're lucky, you might be able to ask the DOL staff to find the case number for you over their service line. But I didn't have that luck. They said they didn't have time to do so and their priority work was to update AVM, which we've all seen the results.
Hope this helps.
