尊敬的8老师，
为国内的父母办绿卡，他们从没来过美国。如果有要公证的，我可以不可以让美国的朋友翻译，在美国的银行公证？因为中国办事太麻烦了，总要求人。
就按这上面说的：
my suggestion to you is that you may ask a friend of yours to translate the birth certificate again, and this friend needs to write a statement addressing that he/she knows both English and Chinese well, and the translation by him/her is accurate for the original document (see the links I cited for you above). Your friend had better go to the Notary Public (e.g. bank) to notarize his/her signature on the translation copy and his/her statement. Also provide the entire copy of your original birth certificate you got 公正 in China though you have provided it when you filed I-485.
行否？
谢谢8老师。
唉，我一天都九问了，不好意思。
