Back from 485 Interview

I am back from 485 interview, which lasted for over 1 hour.
Asked a lot of questions, like what's NIW? EB-2? my research?
Date of birth, where were born, when came to US? What's status now?

VO Took the I-94, photoes, have me and my wife sign the I-551. Finally told me that my name check is not cleared yet. So he can not stamp my passport, but told me once the name check cleared, GC will be sent out righ away.

Is anybody have some idea about how to speed up the name checking process?
