I would like to share with you an information that you might be able to add to the 'Interim EAD Issuance Policy' section. Yesterday, I went to the Orlando, FL office to get my interim EAD. They told me that I had to mail in my request to their office. What they want really is for us to sent them, by mail, another I-765 application, write INTERIM on top of it, attach the I-765 and I-485 receipt and sent it to them by mail.
If anyone's interested: I had an appointment today for H1B visa revalidation. Overall it was a smooth experience. I was asked for my paystubs though.
Degree etc was not asked for. Total interview time was 2 minutes. The only question I was asked was whether I am working for the same company for which I had received an H1 visa previously. In my case that holds true. I also had an F1 visa previously. US Degree.
