Apostille for Dual Citizenship: Descent, Marriage & Naturalization

Definition

What Is Dual Citizenship

Dual citizenship allows an individual to legally hold citizenship in two countries at the same time. Applications are commonly based on citizenship by descent, citizenship by marriage, naturalization, or ancestry. Each country has specific document requirements that must be met before citizenship is granted — applicants must confirm requirements directly with the consulate or government authority.

Requirements

Apostille Requirements for Dual Citizenship

Document requirements vary by destination country and program — not all dual citizenship applications or documents require apostille. For countries that are parties to the Hague Apostille Convention, eligible U.S. documents may be legalized through an apostille. Whether a state apostille or a federal apostille is required depends on the document type and the issuing authority. Foreign records issued outside the United States are not apostilled by U.S. authorities — authentication for those records must be obtained through the issuing country. Incorrect apostille processing is one of the most common reasons for delays or rejection.

An apostille authenticates the official signature and seal on a document — it does not verify the truth of the document's contents, establish lineage, or confirm eligibility for citizenship.

Document Checklist

Documents That May Require Apostille

Depending on the destination country and program, some or all of the following may be required. Which documents need apostille, notarization, or translation depends on the specific program and receiving authority — confirm the exact list with the relevant consulate or immigration authority before preparing documents.

• Birth certificates — official certified copy from issuing custodian required; apostille from issuing state
• Marriage certificates — official certified copy from issuing custodian required; apostille from issuing state
• Death certificates — official certified copy from issuing custodian required; apostille from issuing state
• Divorce decrees — certified copy from issuing court required; apostille from issuing state
• FBI background check, if required — when required: federal apostille (Convention destinations) or federal authentication/legalization (non-Hague destinations); original must not be notarized; state apostille not a substitute
• Naturalization records — obtain in the appropriate agency-certified form; federal authentication route may apply depending on the record and receiving authority; do not use a generic notarized copy
• Name change documents — confirm apostille and authentication requirements with receiving authority
• Court records — obtain certified copies from the issuing court; authentication procedures depend on whether the record is from a state or federal court and on the receiving authority
• Academic records — confirm apostille and authentication requirements with receiving authority
• Power of attorney — state apostille applies after notarization; confirm format with receiving authority
• Notarized affidavits — state apostille applies after notarization; confirm format with receiving authority

Prepare each document according to the program checklist, including any required apostille or legalization, notarization, and translation. Follow the specific checklist provided by the relevant consulate or immigration authority.

Birth & Family Documents

Documents for Citizenship by Descent

Birth certificates are among the most important documents for citizenship by descent applications — they must typically be apostilled and translated for international use. Marriage certificates, death certificates, and divorce records are often required to establish lineage, and may also need to be apostilled and translated before submission. Document requirements depend on the destination country and the specific program — confirm the exact list with the relevant consulate before preparing documents. We process these documents from all 50 states.

Federal Document

FBI Background Check Apostille for Citizenship

Some dual citizenship applications require a criminal background check. When required, the original FBI background check must not be notarized and a state apostille is not a substitute. For destinations that are parties to the Apostille Convention, the federal record is apostilled by the U.S. Department of State in Washington, D.C. For destinations that are not parties to the Convention, a separate federal authentication or legalization route applies instead. Miami Dade Apostille handles federal apostille and authentication processing for dual citizenship applications.

Confirm whether an FBI background check is required for your specific program and destination with the relevant consulate or immigration authority before ordering.

Notarization

Notarization: In-House or Online

Many dual citizenship documents require notarization before apostille. Notarization can be completed in-house at our office in person. Remote Online Notarization (RON) is available where permitted by the signer's location, the document type, and the issuing state's rules — and where the receiving authority accepts RON-notarized documents. RON is commonly used for affidavits, declarations, and other supporting documentation.

Language

Certified Translations for Citizenship Documents

Most dual citizenship applications require documents to be translated into the official language of the destination country. Translation requirements vary by program and receiving authority — some require a sworn or officially recognized translator in the destination country, and a standard U.S. certified translation may not be accepted. Confirm the exact translation format and qualification requirements with the receiving authority before ordering.

Incorrect translations are a common reason for delays or rejection.
