my husband took ME in Beijing on Sept 18. and i took ME in Philadelphia one week later. We cannot get LP untill the Beijing Office receive the FBI non-criminal certificate of me. I'm still waiting for the reply from FBI and so suprisingly that the Embassy called my husband two weeks b4 asking whether i have got the certificate. They also said they would issue the LP as soon as they get my non-criminal document. It seemed that they are even more eager than us..:-)
BTW, we sent out the application package on March 11. See the efficiency of the Beijing Office..
