Please note that the University will only ACCEPT originals or copies of the documents that have been duly declared as true copies
before a notary public (e.g. a Commissioner for Oaths at a District Office in Hong Kong). Copies of documents may be certified by the
appropriate officials of your home institute if you are an overseas applicant.
