To validate a document issued in the United States for use in India, you must first get an Apostille from the state where it was issued. For example, a document that originated in New Jersey must be apostilled in New Jersey.
To be recognized in a participating nation, a document bearing an Apostille does not need to be certified by the US Department of State or legalized by a US embassy or consulate abroad.
Obtaining an Apostille
Before documents issued in the United States can be regarded as legitimate in India, they must be authenticated. Court documents, birth, death, and marriage records, educational paperwork, incorporation papers, and other legal papers are examples of such documents. In the United States, each state issues apostilles for its own documents.
