EAD finally approved at TSC

This is the log of my EAD application:

01/03/2007 E-Filed the application and sent the supporting documents

01/19/2007 Biometrics was taken

04/06/2007 Pending for 93 days with no update since the biometrics. I went to the field office and was told to send an expedite request. The Expedite request was sent by "overnight EMS" on the same day.

04/10/2007 Called the customer service, but they just filed a service referral

04/11/2007 Contacted the congressman's office. They said they would send an email inquiry to CIS

04/13/2007 I was not sure if congressman's office would work on that. So I went to the field office again and the field officer called TSC twice while I was there. TSC duty officer did not explain why the case was delayed but said that the case would be processed immediately.

04/17/2007 Congressman's office called early this morning. They received an email from CIS yesterday saying that the case is with the examiner. Later on, I got a call again from the congressman's office saying that my case has been approved.

I don't know what finally worked (field inquiry, expedite request, or congressman's inquiry). Anyway, I believe it would be further delayed without taking any action.
