My friend had his interview 2 weeks back here in KY. He got his approval yesterday. He used AC 21 portability and changed his job twice. Officer in Louisville was so nice, that he sent my friend to the FP right away (since 1st FP was expired) by calling the FP office (downstairs in the same building). As soon as he got my friend's 2nd FP cleared from FBI, he approved his case. He got his approval in 2 weeks after the interview and FP.
