In order to get IRS Form 6166 (United States Residency Certification) ready for use overseas, it must be legalized. Here are helpful tips to understand this process.
What is Legalization?
The purpose of legalization is to verify the origin of a legal or public document in order to legally use it in a country other than the one that issued it. Legalization is a process of obtaining a series of authentications by individual officials of the country where the document was issued, and then ultimately, of the embassy or consulate of the country where the document will be used. There are only two paths to accomplish this — Authentication and Apostille.

What It Is, And What It’s Not
Authentications and Apostilles certify only the origin of the underlying document and the authenticity of the signature or seal of the signing authority. Neither process certifies the content of the document.
