Also worth trying are Privacy Act requests about data that they have collected on you personally; the Privacy Act is separate from the FOIA, and allows you to request information that they have collected about you. Of course, there is an exemption for information needed for law-enforcement and counter terrorism. So they may simply deny your request (or provide entirely redacted documents) for that reason. But it's still worth a shot. Also remember that technically, it's the FBI which conducts domestic operations. While the NSA may provide services to the FBI to help them collect information, it's the FBI which is officially gathering that information. So any requests, either Privacy Act or FOIA, should be made of both the FBI and NSA.
