ACS给的范例上面有一个certified copy以及证明人签名。<br />
是所有的work reference都要有这个certified copy么?还是复印件的情况下才需要呢?<br />
<br />
我看certified copy上面的定义是<br />
<br />
A document is a certified copy when the original document is photocopied or scanned and a person authorised to certify documents stamps and signs the copy, signifying that it is a true copy of the original document.
