If you search for us residency certification to use abroad, our website: usapostille.com provides it.

We provide apostille attestation service for the US Tax Residency Certificate issued by the IRS, which is used in countries participating in the Hague Convention, because we receive an apostille of US tax residency certificate from the US Department of State in Washington DC. And we help businesses authenticate the document from the US Department of State and legalization from the embassy of the destination country in Washington DC.

If your documents will be used in countries not participating in The Hague, legalization of the embassy is necessary to recognize them. You can order it from our site too.
