Apostille Services for Dual Citizenship
Make your documents valid for dual citizenship applications abroad.
Why You Need an Apostille
Many countries require apostilled U.S. documents for dual citizenship applications, especially for ancestry-based citizenship claims. An apostille authenticates your U.S. documents so they will be legally recognized by foreign governments when you apply for citizenship through descent.
Without proper apostille authentication, your dual citizenship application may be rejected or significantly delayed. Each country has specific requirements for document authentication, and most Hague Convention member countries will only accept documents with valid apostilles.
Common Required Documents
These are the most frequently requested documents for dual citizenship applications:
Long-form Birth Certificates
Official birth certificates showing parents' names and birthplaces
Marriage Certificates
Marriage records of you and your ancestors
Death Certificates of Ancestors
Death records proving lineage and ancestry
Naturalization Certificates
U.S. citizenship documents of immigrant ancestors
Certified Translations
Documents translated into the target country's language
