Whether you need an apostille or embassy legalization comes down to one question: is the country where you’ll use the document a member of the 1961 Hague Apostille Convention? If yes, a single certificate called an apostille is enough. If no, the document has to travel through a three-step legalization chain that ends at that country’s embassy or consulate in the United States. Roughly 129 countries take the apostille; the rest require full legalization.
Both paths exist because foreign governments have no direct way to confirm that a U.S. notary, court clerk, or agency official is real. Authentication builds a chain of verified signatures and seals so the receiving country can trust what it’s looking at. The apostille collapses that chain into one certificate; legalization keeps every link.
Which Countries Take an Apostille
As of 2026, 129 countries participate in the Apostille Convention, including most of Europe, much of Latin America, Australia, Japan, South Korea, India, and Israel. China joined in late 2023 and Saudi Arabia in late 2022, so documents headed to either no longer need embassy legalization. Algeria and Vietnam are scheduled to join in 2026.
Countries that still require the full legalization chain include Egypt, the United Arab Emirates, Kuwait, Qatar, Canada, Thailand, Malaysia, Kenya, and Nigeria. The Hague Conference on Private International Law maintains the current membership list, and the U.S. Department of State determines which certificate to issue based on the destination country you write on your application.
Prepare the Document First
Both paths start with the document itself, and the preparation depends on what kind of document it is.
Public Records
Birth certificates, marriage licenses, death certificates, divorce decrees, court orders, and corporate filings from a Secretary of State’s office are public records. They already carry an official signature and seal, so they go directly to the authenticating authority. They must be originals or certified copies from the issuing agency. Photocopies and printouts are rejected because they lack the raised seal or ink signature the office needs to verify. The State Department also warns against having original public records notarized.
Private Documents
Powers of attorney, contracts, affidavits, academic transcripts, and corporate resolutions come from private parties, so they need notarization before anything else. The notary verifies the signer’s identity and applies a seal, which gives the state or federal office an official signature to authenticate. Without that seal, the submission is dead on arrival.
Confirm the notary’s commission is current and will stay valid through the document’s expected period of use. If the commission expires mid-process, the document can be invalidated. Standard notary fees generally run from a few dollars to around $15, with travel or remote notarization billed separately.
Academic records come with a wrinkle: universities usually will not allow a notary to stamp a diploma or transcript directly. The registrar typically issues a separate letter of authenticity, and that letter is what gets notarized.
Translation
If the destination country requires the document in another language, the State Department advises using a professional translator and having the translation notarized. The translation is a separate document and may need its own apostille or authentication.
The Apostille Path
Where you send the document depends on who issued it.
State-Issued Documents
Documents signed or sealed by a state official, including notarized private documents, go to the Secretary of State (or equivalent) in the state where the document was issued or notarized. Fees run from about $1 to $25 per document. Most states take mail-in requests, some offer walk-in service, and turnaround ranges from a day or two for walk-ins to one to four weeks by mail depending on the state and current volume.
Federal Documents
Documents from federal agencies, such as FBI background checks, patent and trademark certificates, and records from federal courts, skip the state level and go straight to the U.S. Department of State’s Office of Authentications. The fee is $20 per document. Most state documents headed to Hague countries only need the state-level apostille and don’t need federal processing on top.
The Legalization Path
For a non-Hague destination, the same document has to pass through three offices in order.
Step One: State Certification
The document first goes to the Secretary of State in the state where it was issued or notarized. The mechanics match the state apostille process, but the office issues an authentication certificate rather than an apostille.
Step Two: Federal Authentication
The state-certified document then goes to the U.S. Department of State’s Office of Authentications, which verifies the state official’s signature and adds a federal authentication certificate. The fee is $20 per document.
Step Three: Embassy or Consulate Legalization
The final stop is the embassy or consulate of the destination country in the United States. It verifies the federal seal and applies its own stamp or certificate, closing the chain. Consular fees vary widely, from roughly $30 to well over $100 per document. Many embassies require appointments for in-person drop-offs, restrict which couriers they accept for mail, or ask for extras like a cover letter or passport copy.
Because each step has to finish before the next begins, and each office has its own processing window, the full chain can take several months. Build in extra time for shipping between offices.
Submitting to the Federal Office of Authentications
The federal submission process is the same whether you need an apostille or an authentication certificate.
Form DS-4194
Every request needs Form DS-4194. Submitting without it means automatic denial and return of your paperwork. The form asks for your name or company name, contact information, mailing address, destination country, number of documents, and document type. Use black ink, print legibly, and start a new form rather than cross out mistakes.
Fees and Payment
The fee is $20 per document, not per page, and it applies whether the office issues a certificate or a denial. For mail, pay by check or money order made out to the U.S. Department of State; do not send cash or credit card details by mail. Check numbers must be over 100 and the customer’s name and address must be preprinted. For walk-in service, the office takes credit cards, debit cards, and contactless payments like Apple Pay, Google Pay, and Samsung Pay, but not cash, checks, or money orders. All fees are nonrefundable.
Return Envelope
Every mailed request must include a self-addressed prepaid return envelope with your own postage or air bill. The Office of Authentications does not return documents by FedEx and will not split a request across multiple envelopes.
Processing Times
Mailed requests currently take about five weeks or more from the date of receipt. Walk-in requests take two to three weeks overall, with the office processing them within seven business days. Walk-in hours are limited to 7:30 a.m. to 9:00 a.m., Monday through Thursday, capped at one request per day and 15 documents per request. Mail goes to U.S. Department of State, Office of Authentications, 44132 Mercure Cir., PO Box 1206, Sterling, VA 20166-1206.
Common Reasons Requests Get Rejected
- Private documents submitted without a notary seal.
- Notary commission expired at the time of notarization, or set to expire during the document’s expected period of use.
- Photocopies or scanned printouts submitted instead of originals or certified copies.
- Missing Form DS-4194 on federal submissions, which triggers automatic denial with no refund if payment was already processed.
- Wrong destination country listed, which can produce the wrong certificate type and force a resubmission.
- Return envelope with missing postage, a wrong address, or no envelope at all.
What It Costs
For a private document going to a Hague country, plan on notarization (typically under $15), the state apostille fee ($1 to $25), and, if translation is required, a professional translator plus notarization of the translation. If the apostille has to come from the federal office, add $20.
For a non-Hague destination, the costs stack: notarization, state certification, the $20 federal authentication fee, and embassy or consulate legalization fees that vary widely by country. Add shipping for each leg if you’re mailing. A single document through the full chain can easily run $100 to $200 or more once fees, postage, and translation are counted. Professional expediters charge on top of that, and can be worth it if you’re working against a deadline or unfamiliar with the process.
