Moving Abroad? The Ultimate Checklist for Apostilling U.S. Personal Documents
Nobody gets rejected for the reason they expect. Expats bracing for a hard interview or a savings requirement they barely clear almost never get tripped up by either. They get tripped up because their FBI background check was five months old, or because the birth certificate they submitted was the souvenir copy from the hospital, or because they had the document translated before it was authenticated and now the translation is useless.
Consulates do not negotiate on this. They hand the packet back, and by the time you have fixed it your appointment slot is gone and the next one is eleven weeks out. If you have already given notice at work, sold a car, or told a landlord you are leaving, that is not a paperwork problem anymore.
This is the checklist of what typically needs authenticating, which office handles which document, and the mistakes that cost people their appointment dates.
The Two Authorities, and Why It Matters
Every U.S. document you submit abroad falls into one of two buckets, and they are handled by completely different authorities on completely different timelines. Getting this wrong is the single most common reason a packet comes back.
State level. Documents issued by a state or county government are authenticated by that state's Secretary of State. Your birth certificate, marriage certificate, divorce decree, death certificate, and diploma all live here. The state that issued the document is the only state that can authenticate it, which matters more than people realize. If you were born in Ohio, married in Nevada, and currently live in Florida, that is three separate authorities and three separate timelines, and Florida cannot help you with the other two.
Federal level. Documents issued by a U.S. federal agency are authenticated in Washington, D.C., by the U.S. Department of State. Your FBI Identity History Summary is the big one here. No state can authenticate an FBI check, ever. People lose weeks sending FBI reports to their Secretary of State and waiting for a response that is never going to come.
There is also a third situation that catches people: documents you write yourself. Affidavits of single status, letters of financial support, sworn statements about your income, notarized copies of your passport. These are not issued by any government, so they carry a notarial act first, and the authentication attaches to the notary rather than to your statement. A notarization done incorrectly, or done in a different state than where the authentication is being requested, fails.
The Checklist by Document
FBI Identity History Summary
Required for Spain, Portugal, Italy, and most Latin American residency applications. This is federal, so it is authenticated in Washington and nowhere else.
The expiration window is the thing that ruins applications. Many consulates require the report to be issued within the last three months, some allow six, and the clock is running from the date the FBI issued the report, not the date you submit it. Authentication takes time, translation takes time, and mailing takes time. A report that was perfectly valid when you ordered it can easily be too old by the time your appointment arrives.
State police background checks are a separate item. Some consulates accept them, some require them in addition to the FBI report, and those are authenticated at state level rather than federal. Confirm which one your consulate wants before ordering anything.
Birth Certificates
Required for nearly every residency application, and for family reunification, dependent visas, and citizenship by descent.
It must be a certified copy issued by the state or county vital records office, with the registrar's signature and seal. The decorative certificate from the hospital, a photocopy, a scan, and a laminated version are all unusable. Laminated copies are a particular problem because the lamination itself often disqualifies the document.
Some states also apply their own freshness expectations, and several countries want a recently issued copy rather than the one that has been in your filing cabinet since 1987. If your certificate is decades old, expect questions.
Marriage Certificates and Divorce Decrees
Required if you are applying as a couple, bringing a spouse, changing your name on foreign documents, or claiming citizenship through a spouse.
Same rule as birth certificates. It has to be the certified copy from the county or state that recorded the marriage, not the commemorative one from the ceremony. Divorce decrees have an extra wrinkle: they come from a court, and courts often require a clerk certification before the document can move to the state level.
Name changes across documents cause more delays than almost anything else. If your birth certificate says one name, your marriage certificate says another, and your passport says a third, consulates want the paper trail connecting them, and every document in that chain typically needs the same treatment.
Diplomas, Transcripts, and Professional Licenses
Required for work related residency, professional registration, and some digital nomad applications where you are proving qualifications.
These are usually issued by a private institution rather than a government, which means a notarial step comes first. Registrars vary widely in how quickly they will produce a certified transcript, and that is often the slowest link in the chain.
Affidavits, Powers of Attorney, and Support Letters
Required for property purchases abroad, appointing a local attorney or gestor, and proving financial support.
Powers of attorney matter especially for anyone buying property in Mexico, Spain, or Portugal from the United States. The receiving country often has specific wording requirements, and a POA that does not contain the language the local notary expects gets rejected even after it has been fully authenticated. Get the required wording from the receiving attorney or notary in writing before anything is signed.
Country Notes
Spain. Non lucrative and digital nomad applicants consistently need the FBI check plus supporting civil documents, with sworn translation by a traductor jurado. Consulates in the U.S. run different requirements from one another, so the checklist from the Chicago consulate is not necessarily the checklist from Miami.
Portugal. D7 and D8 applicants face the same document set, with the added complication that Portuguese processing has been badly backlogged. That backlog makes freshness windows more dangerous, not less, because the front end of your timeline eats into the validity of documents you already paid to authenticate.
Mexico. Temporary and permanent residency applications, property purchases, and RFC registration all pull in authenticated U.S. documents, and requirements vary between consulates and between states inside Mexico.
Italy. Elective residency and citizenship by descent are the two big drivers. Citizenship by descent is the most document heavy of anything on this page, since it requires a full chain of vital records going back to your Italian ancestor, and every U.S. document in that chain needs the same treatment plus translation.
Where you may not need any of this. U.S. documents generally do not require authentication for the United Kingdom, Canada, Australia, Ireland, or Japan. If someone is quoting you for apostilles on a move to any of those, ask them to show you the requirement in writing first.
The Four Mistakes That Cost People Their Appointment
Translating first. In most countries the authentication certificate itself has to be translated along with the document. Translate first and you will be paying for the translation twice.
Ordering one document at a time. Each document has its own authority and its own timeline. Running them sequentially instead of in parallel is how a three week job becomes a three month job.
Ignoring the expiration clock. The validity window runs from issuance, not submission. Every day spent figuring out the process is a day off the shelf life of your FBI check.
Assuming your neighbor's checklist is your checklist. Requirements differ by country, by consulate, and by visa category, and they change. The person in the expat Facebook group who did this in 2023 is not a reliable source for what your consulate wants in 2026.
