小白兔請幫我看看我的case， 萬分感謝！

幾個月前，Senator幫我查詢FBI, 說我們的name check在兩年前就已經clear 了，而且結果也返回了USCIS。 然後又raise service request to USCIS, 結果USCIS review 了我們的case, 堅持說我仍然stuck 在name check. 來來回回好幾次, 最終落實了是因為USCIS requested another guy's name check with my A#, then that guy's name check got clear which makes FBI believes my name check is clear. 但是奇怪的是, 前幾天我剛剛收到FBI's response regarding my another request through Mrs. Bush, they still claim our name check were cleared 2 years ago...

anyhow, now I am in this screw up situation. i don't know who i should believe to? FBI ? or USCIS? what i should do at this point? I've still asked Senator to check with FBI, but sounds like it is not likely to have any result as she mentioned FBI is like a brick wall to outside inquiry...

Any suggestions / advices what action I should be taking? and Who I should seek for more help to solve this issue?

thanks very much in advance!
