Got it!
Dear All,
Finally the GC arrived yesterday and it is white, not green! Here is the sequence of events after the complaint to the congressman's liason officer, the wonderful Mr. Powers:
Mr Powers told me that TSC got overwhelmed and transferred truckloads of application to CSC. If my husband's application is in that pile, then the original 'receipt date' at TSC (6/7/07) is invalid and the application will be processed by the CSC receipt date (which we didn't know. He called TSC anyway and discovered that my husband's application was not transferred. The application was assigned to a supervisor and TSC promised to take action within 30 days. In about 10 days we got RFE for Medical/tuberculin test. My husband met with the same doctor with the RFE. The doctor prepared another Medical examination form and prepared the answer to the RFE and put it in a sealed envelop which my husband mailed. Meanwhile the lawyer's office also got a copy of our RFE and they told us to contact the immigration doctor asap and do the same. We mailed the answer to the RFE directly back to TSC. Got RFE received update on 7/22/08, GC approved/welcome/card ordered emails on 7/24, welcome letter on 7/31, GC on 8/2.
Finally it is all over - after 14 long years! My heart goes out to those of you who are waiting. I know exactly what it is like. Have courage and patience.
