How to File a FOIA Request: Complete Guide (2026)

The Freedom of Information Act (FOIA) gives any person the right to request records from U.S. federal agencies. The law has been on the books since 1966, yet most requests are still delayed or denied for reasons that have nothing to do with the substance of the records — they're denied because the request itself was vague, sent to the wrong office, or missing a required element.

This guide walks through the whole process the way a careful journalist or researcher would approach it in 2026: pick the right agency, describe your records well, include the right statutory language, and know when to push back.

What FOIA actually covers

FOIA applies only to records held by executive-branch federal agencies. It does not cover Congress, federal courts, state or local governments, or private companies. Each state has its own public-records law for state and local records (Texas has TPIA, California has CPRA, and so on); this guide is strictly about the federal FOIA.

"Records" means documents, emails, photographs, video, and other materials already in the agency's possession. An agency does not have to create a new record to answer a question. If you ask "how many people work in Building X?", the agency can refuse. If you ask "for the personnel roster of Building X as of January 1, 2026," that's a request for an existing record and they're obligated to process it.

Step 1 — Identify the right agency

More than 100 federal agencies process FOIA requests. The first and most common mistake is sending a request to the wrong one. A few heuristics:

• FBI — criminal investigations, counterintelligence, historical files on individuals, internal communications.
• DOJ (Office of Information Policy) — U.S. Attorneys' Offices, Department-wide policy, and coordinates responses for other DOJ components if you don't know which one.
• Department of State — diplomatic cables, embassy communications, visa and passport records.
• DHS / USCIS / CBP / ICE — immigration files, border incidents, travel records.
• EPA — environmental permits, enforcement actions, pollution complaints.
• FCC — consumer complaints, broadcast filings, spectrum licenses.
• SEC — corporate filings beyond EDGAR, enforcement actions, whistleblower records.

Most agencies also have components. FOIA requests addressed to the FBI's Washington Headquarters are not automatically routed to a specific field office, so if you know the records live in San Francisco, address the request to the SF field office directly.

Step 2 — Write a request that actually gets processed

A valid FOIA request has to do three things clearly:

1. State that you are requesting records under the Freedom of Information Act, 5 U.S.C. § 552. This is the magic sentence that triggers statutory obligations and deadlines. Without it, the agency can treat your message as a general inquiry.
2. Describe the records with enough specificity that a professional employee could find them. This is the legal standard (5 U.S.C. § 552(a)(3)(A)). Vague requests are the #1 reason agencies issue "unable to reasonably describe" denials.
3. Agree to pay fees up to a stated amount, or request a fee waiver. If you don't commit to paying fees, many agencies will stop the clock and wait for confirmation.

What "specific enough" looks like

• ❌ "All emails about Topic X."
• ❌ "Everything you have on Company Y."
• ✅ "All emails between [Name/Title] and employees of Company Y between March 1, 2024 and December 31, 2024 mentioning Contract No. 12345."
• ✅ "All enforcement action letters issued by Region 5 between Jan 1, 2023 and Jan 1, 2025 referencing PCB contamination at sites in Wayne County, Michigan."

Dates, names, titles, document types, case numbers, and specific topics are what make a request processable. If you don't have a case number, name a specific event or filing.

The elements every request should include

• Your full name and a mailing address (required by statute).
• A phone number and email (not required by statute but most agencies expect them).
• A clear heading that reads "Freedom of Information Act Request" so the right office routes it quickly.
• The 5 U.S.C. § 552 reference.
• A specific records description (see above).
• A fee provision: "I agree to pay fees up to $25. Please notify me before incurring charges beyond that amount." Or a fee waiver request with justification.
• If time-sensitive, an expedited processing request with justification.
• Preferred format (usually electronic PDF).
• Your signature.

Step 3 — Consider fee waivers and expedited processing

Fee waivers

Fees are waived when disclosure is "in the public interest because it is likely to contribute significantly to public understanding of the operations or activities of the government and is not primarily in the commercial interest of the requester" (5 U.S.C. § 552(a)(4)(A)(iii)).

That's a four-part test: public interest, likely contribution, significance, and non-commercial. Journalists, academics, and non-profits routinely meet it — but you have to argue it. A fee-waiver justification should say who you are, what you'll do with the records, and why that matters for public understanding. Generic "I want to inform the public" is not enough.

Expedited processing

Expedited processing is a higher bar. You must demonstrate a "compelling need," which generally means either (1) an imminent threat to someone's life or physical safety, or (2) an urgency to inform the public about actual or alleged federal government activity and you are primarily engaged in disseminating information. Both prongs are narrower than they sound — courts and agencies read them strictly.

If it applies, say so clearly and certify that the statement is true and correct.

Step 4 — Submit through the right channel

Most agencies accept FOIA requests through at least two of these channels:

• FOIA.gov (a federal portal that forwards to most agencies).
• Agency-specific online portal (usually faster and generates a tracking number).
• Email to the FOIA office.
• Postal mail.

Online portals are generally the fastest and produce a reliable paper trail. Email is next. Physical mail is slowest and easiest for agencies to lose.

Whichever channel you pick, keep a copy of what you sent. Include a dated signature block. If you file by email, a short cover note pointing to the attached formal request helps the routing clerk.

Step 5 — Track, follow up, and appeal

By statute (5 U.S.C. § 552(a)(6)(A)(i)), the agency must respond within 20 business days (roughly a calendar month). In practice, backlogs mean that deadline is missed constantly. What still matters:

• Get a tracking number. Every agency must assign one.
• Follow up after 20 business days if you've heard nothing.
• Respond to narrowing offers promptly. If the FOIA officer offers to narrow the request in exchange for a faster response, take the call — it's often the best way to unblock a large request.
• If denied, appeal. Every denial letter must explain appeal rights. Appeals are usually due within 90 days and go to a different office. Appeals are free and reverse decisions more often than people expect.

Common mistakes that waste weeks

• Addressing the request to the wrong agency or component.
• Writing "all emails about X" without dates, names, or document types.
• Forgetting to include the 5 U.S.C. § 552 reference.
• Omitting mailing address (statutory requirement).
• Asking questions instead of requesting records.
• Not committing to pay fees and not requesting a waiver — the request just sits in an inbox.
• Requesting expedited processing without meeting the statutory criteria.
• Ignoring narrowing-offer calls from the FOIA officer.

When to get professional help

If you're filing a single request and have the time to iterate, the process above is entirely doable yourself. If you're filing several, filing under a deadline, or preparing a request that's likely to face pushback, having a template that already includes the statutory citations, fee-waiver language, and agency-specific formatting saves a lot of round-trips.
