有國內的一些材料，我打算找朋友翻譯簽名。按照這裏http://www.uscis.gov/forms/forms-and-fees/general-tips-assembling-applications-mailing 的解釋，我隻要附上說明就可以了。
問題是朋友的簽名需要找這邊的public notary公證嗎？還是並不需要？
謝謝了！
The certification format should include the certifier's name, signature, address, and date of certification. A suggested format is:
Certification by Translator
I [typed name], certify that I am fluent (conversant) in the English and ________ languages, and that the above/attached document is an accurate translation of the document attached entitled ______________________________.
Signature_________________________________
Date Typed Name
Address
