接到FBI关于NAME CHECK的回信,请大家帮忙看看

I140 EB1a filed April,2003; approved Oct.2004.
I485 filed on Feb.2005, still pending...

给USCIS写信,打电话, 给SENATOR写信, 回复说仍在FBI做NAME CHECK.

12月给FBI写信问我的NAME CHECK的情况, 今天收到回信:

To prompty respond to requests, we concentrate on identifying mail files in the certral records system at FBI Headquarters. No records responsive to your FOIPA request were located by a search of the automated indices.

哪位朋友有类似经历或明白这其中的意思, 请解晰一下. 多谢!
