More Update
Just spoke to INS (Finally), the officer at the other end tried to be rude, but I kept my temperment cool and was very polite.
When told about my approval and my sons, she was kind of curious (well our cases were filed in Feb 2000, nothing to be curious).
She told me that My wifes case is not yet assigned to an officer (need to wait). She informed me that there are several 1000 cases ahead of my wifes, and usually the supervisor assigns the case to an officer. After telling her "Appreciate your help", she said sure and took my SRC number also, and told me she will request the supervisor to assign the case to an officer, but it is supervisors sole discretion.
Will wait for one more month and if no progress, will send request to senators.
