-国内公证 should contain the 原件的复印件, right?
2.我的出生证明是在98年公证的,是否还有效?
-Yes.
当时的公证书没有附Cettified Translation以证明公证文件的英文翻译是true and exact translation,我可以自己写一个证明吗?
-You may ask one of your friend to translate it English and notarize your friend's signature at a Notary Public. Your friend also need to write statement addressing that he/she knows both English and Chinese well and the translation is accurate.
