if you have done interview, by law they have to adjudicate your case within 120 days, 見這裏 so if you are over 120 days, just file 1447(b), they will act within 1-2 months. Recently we help 3 similar cases, see 見這裏
anyway, if you are stuck with name check, and particularly you have done interview, then the best choice is file WOM, or wait for uncertainly period (even though no one know how long for NC to clear)
