公民给母亲办绿卡所需要的亲属关系公证原件找不到了,
-It is OK to provide the photocopy.
请问亲属关系公证可以在美国办吗,
还是要回国去办?
-Yes, but this document is not required officially though some immigration officers may ask for it. If needed, you may just ask the original notarization agency to issue a copy to you (Perhaps they may still have your file there).
非常感谢!
