Is Sri Lanka a Hague Convention country?
No. Sri Lanka is not a party to the Apostille Convention, so an apostille will not be accepted there. The document needs U.S. Department of State authentication first, then legalization at the Sri Lanka embassy or consulate — in that order.
The route to Sri Lanka
A IRS Form 6166 is issued by Internal Revenue Service, a federal authority, so it is authenticated by the U.S. Department of State in Washington, D.C. — never by a state office. For Sri Lanka, the Department of State’s authentication is then legalized at the Sri Lanka embassy or consulate.
People most often send documents to Sri Lanka for family and employment matters. Receiving offices set their own requirements, so confirm what yours asks for — we’ll help you read it.
