1）130阶段，是不是父母的那些出生公证，结婚公证，亲属公证都不需要？我总觉得不提交不放心的感觉，但是又没有地方提交。
-Your need to submit the copy of your parents' marriage certificate for the I-130 for your father's, not need it for your mother. Also you need to provide the copy of your birth certificate for the I-130 for both your parents.
If you have 亲属公证, then just provide it for both parents (not required, but optional) and if you don't have it, not need to provide it. You also need to provide the copy of your US citizenship proof or US passport.
2）130 还要school record和census record，这个是不是optional的？从未听说其他人交过啊
-Not need.
3）有一向问beneficiary 的 class of admission, 还说在绿卡上有这个标记，可是还没有绿卡呢，这个是不是也是optional的不用填写？
-Leave it blank or put "N/A" if your parents are currently present in China and will apply for the immigrant visa in China later.
