Thanks Amcom,
Without wasting a minute, I have e-filed I-765 application for me and my wife. Yes my wife is working with EAD which expires a day ahead of mine (04-01-04). After filing, I called the NSC IIO to get an appointment for photo and finger priniting. We hgot one for tomorrow morning 8.00 AM at locas ASC. She also said, no way I can get an interim EAD from local service centers. She had very happily declared that even if I attempt one, it is my waste of time! So, now I have to sit tight and pray god. USCIS makes every immigrant's life miserable.
Anyway, thanks for timely advice and as you have suggested, I will have to go to INS district office in Santa Ana to get an Interim EAD if I don't receive one before that. I appreciate if you could pass any info related to my case.
