回複：求：EB based 485 interview 經驗

Do not worry too much. I had interview in local office in May 2007(my case is EB-2, employement based) No tricky questions, just go through the info you already provided to USCIS. The interview is about 10min(for me) and since my background check is clear, so she stamped on my passport right away and took away all my I-94(s) and EAD. You need to prepare your birth certificate, tax returns for last 3 years (though only recent 1 year needed), last 3 pay checks, employment verification letters and all the copies or original notice you received from USCIS and so on.
