Embassy Legalization Services

Embassy legalization services involve authentication of your legal documents. This is done at an embassy in the US to verify the validity of the document that is for use in another country. When traveling to another country, you may need the legalization services when: getting married, working, planning to move … or many other situations.

The Hague Convention of 1961 established a uniform system to validate documents. Countries that are members of this convention follow the apostille process to authenticate documents. One Source Process provides apostille services as well as legalization services.

State-issued and federal-issued documents have separate processes. State-issued documents (such as a driver’s license, birth certificate, death certificate, marriage license, divorce decree) must receive state certification, then be certified by the US Department of State in Washington DC, and finally, receive embassy legalization.
Federal-issued records (such as Social Security records, FBI background check, certificate of naturalization) skip the state certification step and move directly to being certified by the US Department of State in Washington DC, and then receive embassy legalization.

The embassy authentication (or consular legalization) process can be complex; missteps can result in frustrating delays or total rejections.
