GLSAS  provides certified translations as well as notarization if requested. We individually certify each document submitted so as to maximize document reusability and insure the highest quality. To certify a document means to vouch for its contents. Therefore we only certify translations performed by us. By proofing the translation against the source we state that it is a true and accurate translation, to the best of our knowledge.
A certification ensures that the document is a valid translation and may be used for legal purposes.

The notarization certifies the authenticity of the translator's signature.

The certification and notarization of translations are routinely required for immigration and naturalization, academic, and professional purposes.

Documents issued and having legal effect on the territory of one country can be used on the territory of another country only after their legalization in accordance with the established procedure unless otherwise is provided for by the legislation of countries or international contractual provisions which repeal the authorization procedure participants of which are countries. At present the most common method of this certification is the Apostille.
