US Apostille is a non stock entity, established to simplify the process of obtaining an apostille in the United States. You do not need to pay for a courier to obtain an apostille, you can do it by yourself. Many private agencies offer apostille services online at high prices. The truth is that you do not need their services at all. You can get an apostille simply by mailing your document directly to the Secretary of the State in which it was notarized or issued.
