回複：請皮大師、8大師和各位達人幫助出個主意

我現在辦理移民，也碰到老人公證那些問題，後來看了幾個帖子，通過“走後門”，找關係，我們的出生公證（有去世多年父母名字）可以辦了，但是婚姻公證因為我們曾經經曆文革、戰備搬遷、工作調動、換房搬家有8次之多，結婚證有可能丟失，也有可能壓在那裏，國內親友不可能找到，公證處不給辦理婚姻公證。
-讓派出所，街道居委會，或原單位的人事部門出個證明，然後再去公證。

請各位支招，我們用什麽方法（戶口本、親友證明、單位證明）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 婚姻公證 .
