請問這是什麽意思？謝謝。

I-485久沒消息，所以file了FOIPA to FBI. 現在收到這樣的信，請問是什麽意思？大家有類似的情形嗎？謝謝。485 是07-xx-2006.

To promptly respond to requests, we concentrate on identifying main files in the central records systems at FBI headquarters. No records responsive to your FOIPA request were located by a search of the automated indices.

you may file an administrative appeal by writing to the director,.............., within 60 days from the date of this letter. The envelope and the letter should be clearly marked" freedom of information appeal" or "information appeal" ....

I did search the forum but don't find "information appeal" info.

any input is really appreciated.
