Document attestations through the Embassy are done in three steps. Your documents are typically certified at the state level as the initial step. Your documents must first be certified by the State before they may be certified by the U.S. Department of State in Washington, D.C., unless they were issued by the U.S. Federal Government. The U.S. Department of State in Washington, D.C., must certify your documents as part of the second phase. The Oman Embassy in Washington, D.C., must certify your documents as the last stage.
Apostilles may be challenging. Don't trust this technique to untrained workers or unqualified individuals who are unaware of the Apostille procedure and the particular needs of several countries. Your paperwork can be turned down, which would cost you time and money. Be awared!
