You must authenticate the certificates if you want to use US documents in the UAE. The Ministry of Interior does not recognise any paperwork or formal agreement in the US unless it has been certified. The authentication of US identity documents, mail copies and forwarding of certified copies and credentials makes them valid and legitimate. It confirms an individual's birth, marriage, degree or diploma certificate. The US postal services make certified copies of US papers. The same procedure is used in UAE courts and ministries. Individuals or families who want to travel to UAE have to attest their US certificate, which helps them with business, schools, colleges, seeking jobs and visas.
