Which Federal Documents Can Be Apostilled
Federal documents apostilled by the U.S. Department of State include IRS records, USDA and FDA certificates, USPTO filings, federal court documents, military records, USCIS citizenship certificates, and Consular Reports of Birth Abroad. If a foreign government, bank, tax authority, or court has asked you for an apostille on one of these documents, it cannot be issued at the state level — federal documents follow a separate path through the Office of Authentications in Washington, DC. This guide covers each major category of federal document, what the underlying document actually is, and where to go for the full requirements on the document types we cover in depth elsewhere.
How Federal Documents Differ From State Documents
The single most common point of confusion in the apostille process is which office issues the apostille. Documents issued or notarized at the state level — birth certificates, marriage certificates, diplomas, powers of attorney, and most business records — receive their apostille from the Secretary of State of the state where the document originated. Documents issued by an agency of the U.S. federal government follow a different route entirely: they are apostilled only by the U.S. Department of State's Office of Authentications in Washington, DC. A state office has no authority to apostille an IRS letter or a federal court order, and the Department of State will not apostille a state birth certificate. Before you begin, identify who issued your document — if the letterhead or seal belongs to a federal agency, everything on this page applies. Federal apostilles typically take roughly 10 business days when filed in person in Washington, DC, compared to 8–12 weeks when submitted by mail.
IRS Form 6166 and Other IRS Record Apostilles
The most frequently apostilled IRS document is Form 6166, the Certificate of U.S. Tax Residency. Foreign tax authorities request Form 6166 when a U.S. individual or company wants to claim benefits under an income tax treaty or obtain an exemption from a foreign country's value-added tax. You request the certificate from the IRS by filing Form 8802 (Application for United States Residency Certification); the IRS then issues Form 6166 on official letterhead bearing a facsimile signature and seal, which the U.S. Department of State can apostille directly. Other IRS records — such as account transcripts or official IRS correspondence — can also be apostilled, provided they are original documents issued by the IRS with an authorized signature; ordinary photocopies of your own tax returns do not qualify on their own. Because Form 6166 is issued for a specific tax year, check that the year on your certificate matches what the foreign authority is asking for before submitting it for an apostille.
DD-214 and Military Record Apostilles
The DD-214 is the Department of Defense's Certificate of Release or Discharge from Active Duty, and it is the military document most often requested abroad — typically for foreign residency applications, overseas pension or benefit claims, foreign employment, or immigration processes that ask for proof of U.S. military service. Because the DD-214 is a federal document, it is apostilled by the U.S. Department of State, not a state office. The Department of State generally requires either an original or a certified copy issued by the National Personnel Records Center (NPRC) or the relevant service branch; veterans who no longer hold their original can request certified copies of their military records through the National Archives. Other military records — service verification letters, records of emergency data, and similar personnel documents — follow the same federal path when they carry an official DoD signature and seal. Plan ahead: obtaining a certified copy from the NPRC adds its own processing time before the apostille step even begins.
Social Security Letter Apostilles
Social Security Administration documents come up most often when a U.S. retiree living abroad, or a foreign institution handling their affairs, needs official proof of benefits. The typical document is an SSA benefit verification letter (sometimes called a proof-of-income or budget letter), which states the benefits a person receives; foreign pension offices, banks, and immigration authorities may require it with an apostille before they will accept it. Because the SSA is a federal agency, these letters are apostilled by the U.S. Department of State. The letter must be an official SSA-issued document with an authorized signature — a printout of an online account screen generally will not qualify, so request an official letter from the SSA directly. Other SSA correspondence, such as award letters, can follow the same process when the foreign receiving party asks for them in authenticated form.
Federal Court Document Apostilles
Documents issued by U.S. federal courts — orders, judgments, and certified copies of case records from courts such as the U.S. District Courts — are federal documents and are apostilled by the U.S. Department of State. This category is distinct from state and county court documents, which go through the state Secretary of State instead, so the first step is always confirming which court system issued your document. Federal court records generally must be certified by the clerk of the issuing court before the Department of State will apostille them.

USDA and FDA Certificate Apostilles
Exporters of food, drugs, cosmetics, medical devices, and agricultural products regularly need federal certificates apostilled for foreign regulators. The most common are the FDA's Certificate of Free Sale and Certificate to Foreign Government, and the USDA's export and Phytosanitary Certificates. Because both agencies are federal, these certificates are apostilled by the U.S. Department of State, and foreign import authorities frequently will not clear a shipment or register a product without the apostilled version.

USPTO Patent and Trademark Apostilles
Certified copies of patents, trademark registrations, and related filings issued by the U.S. Patent and Trademark Office are apostilled at the federal level for use in foreign IP registrations, licensing deals, and litigation abroad. The key requirement is that the USPTO itself issue a certified copy of the record — the certified copy, not your own courtesy copy, is what the U.S. Department of State apostilles.

Certificate of Naturalization Apostilles
Naturalized U.S. citizens are regularly asked to prove their citizenship abroad, and the Certificate of Naturalization — Form N-550, or Form N-570 when issued as a replacement — is the document that does it. Because USCIS is a federal agency, the certificate is apostilled by the U.S. Department of State rather than a state Secretary of State, which surprises many applicants who assume citizenship paperwork follows the same path as a birth certificate. The Department of State authenticates the original certificate or a USCIS-issued certified true copy; an ordinary photocopy will not qualify, and reproducing the certificate outside lawful channels is restricted.

Certificate of Citizenship Apostilles
A Certificate of Citizenship — Form N-560 or N-561 — is the USCIS document issued to people who acquired or derived U.S. citizenship through a parent rather than naturalizing themselves, most often children born abroad to a U.S. citizen parent or children whose parent naturalized before they turned 18. It follows the same federal route as the naturalization certificate: the U.S. Department of State issues the apostille, and no state office can. Foreign civil registries, courts, and immigration authorities commonly request it in apostilled form when handling dual-citizenship claims, residency applications, and estate matters.

Consular Report of Birth Abroad (CRBA) Apostilles
Form FS-240, the Consular Report of Birth Abroad, records that a child born outside the United States acquired U.S. citizenship at birth through a U.S. citizen parent. It is issued by a U.S. embassy or consulate under Department of State authority, which makes it a federal document — sending it to a state Secretary of State is a common and costly mistake, since the state office has no authority over federal records. The CRBA is also the one federal document that cannot currently be filed in person or expedited: the Department of State requires these requests to be mailed in, so plan on roughly 8–12 weeks regardless of who files.
Getting Your Federal Document Apostilled
Every document above shares the same bottleneck: the U.S. Department of State's Office of Authentications in Washington, DC, where mailed submissions currently run about 8–12 weeks. Federal Apostille™ files in person in Washington, DC, which brings typical turnaround to roughly 10 business days, and we review your document before submission so a missing certification or wrong document version doesn't cost you a rejection and a restart. If you need an IRS, military, SSA, court, FDA/USDA, USPTO, or USCIS citizenship document apostilled — or you're not sure whether your document is federal or state — start your order and we'll confirm the correct path before anything is filed. The one exception is the Consular Report of Birth Abroad, which the Department of State requires to be mailed in; we're not filing those directly right now, and our CRBA guide walks you through the mail-in steps.
Frequently asked questions
Can my state's Secretary of State apostille an IRS letter or DD-214?+
No. State offices can only apostille documents originating in their state, such as notarized documents and vital records. Anything issued by a federal agency — the IRS, DoD, SSA, FDA, USDA, USPTO, or a federal court — must be apostilled by the U.S. Department of State in Washington, DC.
Do I need a notary before a federal document can be apostilled?+
Generally no. Federal documents like Form 6166, a DD-214 certified copy, or an SSA benefit letter carry an authorized federal signature and seal, which is what the Department of State authenticates. Adding a notarization to a federal document doesn't help and can cause confusion — notarized documents route through state offices instead.
What if the country receiving my document isn't in the Hague Apostille Convention?+
An apostille only works for countries that are party to the Hague Apostille Convention. For non-member countries, the same federal documents instead need authentication by the U.S. Department of State followed by legalization at that country's embassy or consulate. Confirm the destination country's status before ordering.
