如果去notary public翻译， 还需要在那里公证吗？

如题，因为ica网站上写
(i) Translations provided by the embassy of the country that issued the document
(ii) Translations produced by a notary public in Singapore or the country that issued the document
(iii) Privately created translations attested by the embassy of the country that issued the document, or notarised by a notary public in Singapore or the country that issued the document.


所以根据（ii）写的， 如果是在notary public翻译的， 就不需要再notarise/公证了吗？

还有如果要公证，是所有的翻译文件都需要，还是选择性的呢？我目前有出生证明，关系证明，改名字证明，和小学毕业文凭需要翻译。

请各位指点一下我， 谢谢了~
