8老师，
我打算为我父母申请绿卡。有几个问题想请教一下8老师：
1. check是父母每人一张check（485+bio+130），还是父母每人两张（一张485+bio 和 一张130）？
2. 读了130的instructions：
F. A mother: Submit a copy of your birth certificate showing your name and your mothe’s name.
G. A father: Submit a copy of your birth certificate showing the names of both parents. Also submit a copy of your parents’ marriage certificate establishing that your father was married to your mothe. If either your mother or father were previously married, submit copies of documents showing that each of the prior marriages was legally terminated. If you are filing for a stepparent or adoptive parent, or if you are filing for your father and you werborn out of wedlock, see Items D., H., and I. in these Instructions for additional information on proving your family relationship.
是不是说母亲的130 package 只要出生公证，而不用婚姻公证，只有父亲的130 package 需要both？
3. 是不是父母申请绿卡只用填130，485，864，693 （from doctor），而不需要g-325a和i-130a？
多谢！
