EAD applied for L2 Dependent Visa

[DhirajGa]

Dear Sir/Madam - Hope you doing good !

We have applied for a EAD for my spouse who is on L2 visa.

We have received a Form I-797C, Notice of Action with the following information

Notice Type - Receipt

Case Type - I-765, Application for Employment Authorization

Receipt Number - ******** (13 digits)

Received Date - April 03, 2012

Notice Date - April 5, 2012

USCIS Alien Number - It's blank

The contain says - that The above application/petition has been received by our office and is in process

It also has a note which says

Please note that if a priority date is printed on this notice, the priority does not reflect earlier retained priority dates.

When we tried to search the case status by providing the Receipt Number on uscis.gov site, it say - cannot find the information/case.

Can you please suggest what should be the next step ?

Thanks in advance

Regards
