回复：请皮大师、8大师和各位达人帮助出个主意

我现在办理移民，也碰到老人公证那些问题，后来看了几个帖子，通过“走后门”，找关系，我们的出生公证（有去世多年父母名字）可以办了，但是婚姻公证因为我们曾经经历文革、战备搬迁、工作调动、换房搬家有8次之多，结婚证有可能丢失，也有可能压在那里，国内亲友不可能找到，公证处不给办理婚姻公证。
-让派出所，街道居委会，或原单位的人事部门出个证明，然后再去公证。

请各位支招，我们用什么方法（户口本、亲友证明、单位证明）可以使移民局接受？
-Although the US citizen's father needs to provide his marriage certification based on the I-130 instructions, but some people did not provide this document and got their green card. It seems USCIS is not strict to require the US citizen's father to provide his marriage certificate for the I-485 application. So, your father may just take a shot if you can not get the 婚姻公证 .
