回複：請問有結婚證,在美國能辦理公證嗎,怎麽辦?

Just ask your friend to translate it into Englsih and then, go to the bank to notarize your friend's signature in the translation copy and also notarize your Chinese photocopy (verify that it is the copy of the original one). Your friend also need to make a statement that he/she knows both Chinese and English very well.
