本人因怀疑被NAME CHECK，所以写信要求FOIPA。不久受到回信显示NO RECORD如下
"A search of the automated indices to our central record system files at FBI Headquarters located no records responsive to your FOIPA request."
但是后面又有一段说我可以FILE administrative appeal；
"Although no records responsive to your FOIPA request were located in our automated indices, we are required to you that you are entitled to file an administrative appeal if you so desire"
请问各位“administrative appeal”是什么意思，我到底需不需要FILE这个APPEAL。谢谢
