Recently I have been to Baltimore District Office to collect my interim EAD, I was told that if INS Processing Center(Vermont) requested some additional documentation, that requested documentation should be sent to Vermont(that information should be updated in INS database), then only they can issue interim EAD. They are taking 30 days to issue Interim EAD.
I walked in to the Detroit USCIS Center on Monday Sept 9th 2003 at 11:30pm. They gave me the waiting number & gave me an application form for Employment Authorization. At around 3:00 pm the duty officer wanted receipt notices (over 90-day proof), the original I-765 application, I-94 & driving licence (proof of picture ID). She asked me to get photo copies of each of these documents, which I got it immediately for her. After an hour someone called my name and took my picture and provided the card good for 6 months.
