A certified copy is a copy of an original document that has been certified by an authority authorised to certify documents. A certified copy can be obtained from a public authority, a document's issuing body or another official body, in a document's issuing country.

Note that original documents need to have been legally authenticated, by apostille certification or chain authentication (double verification) before making and confirming copies.

You can also submit original documents with your application and get them back after the application process.
