Not all French-speaking countries are members of the Hague Apostille Convention. For documents from non-member countries, the apostille process does not apply — you need consular legalization instead, which is a different and longer process.
Hague Convention members (apostille available): France, Canada (including Quebec), Senegal, Cameroon (since 2023), Morocco, Tunisia. For these countries, the apostille process works as described above (though the issuing authority varies by country).
Non-members (legalization required): Haiti, Democratic Republic of Congo, Ivory Coast, Mali, Burkina Faso, Guinea, Chad, Central African Republic, Madagascar, and several other Francophone African and Caribbean nations. For these countries, documents must go through consular legalization, which involves the document passing through the foreign ministry of the issuing country and then the U.S. embassy or consulate in that country.
Haiti is a particularly important case for French-language translation: Haitian documents are among the most commonly translated French-language documents for U.S. immigration, but Haiti is NOT a Hague Convention member. This means Haitian birth certificates, marriage certificates, and court documents cannot be apostilled — they require legalization. For in-depth coverage of Haitian documents, see our Haiti document translation guide.
The translation requirement remains the same regardless of whether the document is apostilled or legalized: a complete certified English translation with a signed Certificate of Accuracy is required for USCIS, courts, and universities. The authentication method (apostille vs. legalization) does not change the translation process.
