Apostille Certificates for International Use: U.S. Guide for 2025

(Power of Attorney and Birth Certificates Focus)
If you’re planning to use your U.S. documents in another country, you’ll most likely need an apostille — especially for essential papers like a Power of Attorney or a birth certificate. This certification makes your documents legally valid abroad, ensuring they’re accepted by foreign authorities.
Below, we explain how apostilles work in the U.S., which documents qualify, and what to know if you’re handling sensitive personal or legal paperwork.
What Is an Apostille?
An apostille is a one-page certificate that authenticates the origin of a public document for use in countries that are part of the Hague Apostille Convention. Once attached, it confirms that your document is valid and can be legally recognized by foreign governments — without additional legalization.
Apostilles are commonly needed for:
- Immigration and visa applications
- International marriages and divorces
- Dual citizenship
- Business transactions abroad
- Academic or medical purposes
- Legal representation overseas
Apostille for Power of Attorney (POA)
If you are authorizing someone to act on your behalf in another country — for example, to manage property, handle a bank transaction, or represent you legally — a Power of Attorney (POA) will likely be required. But notarizing it is not enough.
In nearly all cases, the foreign institution will demand a properly certified and apostilled copy of the POA.

When preparing a POA for international use, make sure:
- It’s notarized correctly, with a legible signature and complete acknowledgment
- It meets the language and formatting requirements of the destination country
- You submit the original (not a photocopy) for apostille
We assist clients nationwide with preparing, notarizing, and apostilling POA documents — including translations if needed.
Apostille for Birth Certificate
One of the most requested services in 2025 is the apostille for a U.S. birth certificate. This document is often required when applying for:
- Dual citizenship
- Foreign marriage registration
- School enrollment abroad
- Family-based immigration petitions
But not all birth certificates are eligible. To qualify for an apostille:
- It must be a certified copy issued by the appropriate state vital records office
- Hospital or souvenir certificates will not be accepted
- In many cases, you’ll need to request a new certified copy if the original is outdated or damaged

How the Apostille Process Works
Here’s a simplified version of how apostille processing works in the U.S.:
- Review your document
Confirm that it qualifies (notarized or government-issued, depending on type) - Notarize if required
POAs and some letters need proper notarization before apostille - Submit to the correct state or federal office
Each state handles its own documents; federal documents go to the U.S. Department of State - Apostille is attached
A one-page certificate is affixed, verifying the document for international use - Return delivery
We return it to you via trackable domestic or international shipping
