Is Italy a Hague Convention country?
Yes. The Apostille Convention has been in force for Italy since 11 February 1978, and for the United States since 15 October 1981 — so a U.S. apostille is accepted in Italy with no embassy step.
The route to Italy
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 Italy, that apostille is the finish line.
People most often send documents to Italy for citizenship by descent (jure sanguinis), property, residency. Receiving offices set their own requirements, so confirm what yours asks for — we’ll help you read it.
