43 CFR § 2.4 - Does where you send your request affect its processing?
(a) A request to a particular bureau or a bureau component (for example, a request addressed to a regional or field office) will be presumed to seek only records from that particular bureau or component. A request will not be forwarded to another bureau or component unless it is clear on the face of your request that it was misdirected. For example, if you address your request to an appropriate FOIA contact in the National Park Service and ask for records concerning a specific park, but your request is delivered to the Fish and Wildlife Service, your request was clearly misdirected. In such a case, a FOIA contact in the receiving bureau or component will route the request to a FOIA contact in the proper bureau or component. If you need assistance determining where to send a request, you may seek assistance from the bureau's designated FOIA contact or FOIA Requester Center (see § 2.66 of this part).
(b) If you seek records from an entire bureau, submit your request to the bureau FOIA Officer. The bureau FOIA Officer will forward it to the bureau component(s) that he or she believes has or are likely to have responsive records.
(c) If a request to a bureau states that it seeks records located at another specific component of the same bureau, the appropriate FOIA contact will forward the request to the other component.
(d) If a request to a bureau states that it seeks records from other unspecified components within the same bureau, the appropriate FOIA contact will send the request to the Bureau FOIA Officer. He or she will forward it to the components that the bureau FOIA Officer believes have or are likely to have responsive records.
