Certified Translations
LinguaOne’s certified translations are delivered with a Certificate of Accuracy signed by the translator confirming it is a complete and accurate translation.
Certified translations are required for immigration documents such as USCIS birth certificates, as well as business contracts, court files, and other legal documents.
Notarized Translations
If needed, we will have your translation notarized, which will authenticate the identity of the signing translator.
For example, notarized translations are often requested by universities for academic transcripts and diplomas in a foreign language.

One-page documents such as standard birth certificates and marriage certificates typically range from $60 to $90.
For multi-page documents, the cost will depend on several factors including the document’s word count, how common the language combination is, the amount of special formatting required, and the level of specialization needed for the subject.
For one-page documents, certified translations are often delivered in 1 to 3 days.
Regarding multi-page documents, the turnaround time will vary depending on the length and complexity of the document.
If you need your document delivered in less than 24 hours, we offer an expedited translation service for a fee of $150.
Certified translators are individials who have passed an official exam to determine their ability to translate from one language to another.
LinguaOne translators are often linguists with a degree in the language they are translating and have typically traveled significantly abroad or lived in the country where the language is spoken as well.
We will need to review your documents to provide a final quote. However, you can request a translation estimate by providing the following document information:
