You want to ask a specific agency for all documents regarding Mexico? That would probably get thrown out as too vague. Maybe you have a specific event in mind? That would be much better.
My question has nothing to do with me trying to file FOIA requests, but rather how can I access documents you have already declassified regarding Mexico which I believe you have posted in your website. Usually one can search for “Mexico” and all documents related to Mexico show up but I don’t see a search option in your web page. Thanks.
