回複：求教各位大神。。。

老公的爸爸已經在美國境內是綠卡身份，當時來的時候與他媽媽離婚了。。

後來來美國2個月後回國複婚了。。

老公現在是公民想要申請他媽媽來美國，請問他媽媽的婚姻狀況能不能用當年的離婚公證呢？
-Not need it under your spouse's sponsor (son sponsors mother).

不填寫複婚狀態，移民局會查出來他是與他爸爸複婚嗎？
-Irrelevant to the green card application, but she needs to report her two-time marriage in the Form I-485 even if she married the same hu*****and two times.
