Apostille of documents for dual citizenship
If a consulate, municipality or citizenship professional has told you which U.S. records you need, we coordinate the authentication side: identifying the competent authority for each document, whether state, county or federal, and apostilling them for use abroad. We don't determine eligibility, that's a question for the receiving country's consulate or your citizenship professional.
Multi-document cases welcome · State, county and federal, coordinated together · We don't determine eligibility
We coordinate authentication, not eligibility
Citizenship-by-descent and dual-citizenship cases often require several U.S. documents from different sources at once: birth, marriage or divorce certificates from one or more states, court or naturalization records, and sometimes federal records. Our role is identifying the correct authority for each document you already know you need, whether that's a state vital records office, a county clerk, or a federal agency, and coordinating the apostille or, if applicable, consular legalization.
We do not determine which documents your specific case requires, that's a question for the receiving country's consulate, municipality, or your citizenship professional. Once you know the list, we handle the U.S. side.
Documents commonly involved
State vital records
Birth, marriage, death and divorce records, each apostilled by the state where it was issued or recorded, not where you currently live.
Multi-state files
If your documents come from more than one state (for example, a grandparent's record from one state and a parent's from another), each document follows its own state's process independently.
Naturalization and federal records
Certificates of naturalization and NARA-held records are apostilled by the U.S. Department of State, not any state. Getting a naturalization certificate ready for apostille typically requires an in-person appointment at a USCIS office first, to obtain a Certified True Copy, before it can be sent for authentication.
Certified copies only
Every document needs to be an original certified copy. A photocopy is not eligible for apostille.
Three steps for a multi-document file
Send us your document list
The list your consulate, municipality or citizenship professional gave you, and which state, county or federal agency issued each one.
We map each document to its authority
We confirm which authority applies to each document on your list and flag any that need a prior step, like a naturalization certificate needing a USCIS appointment first.
We coordinate the full file
We coordinate the apostille for each document as its authority allows, so you can track your whole file instead of managing several separate processes.
