隻有要求下麵的人提供結婚證明：
Marriage Certificate and Other Proof of Family Relationship：
If you are filing Form I-485 as the derivative applicant spouse of the principal applicant, you generally must submit a photocopy of your marriage certificate issued by the appropriate civil authority where the marriage took place......
能否拜托確定一下？另外父母除了提交自己的出生公證，還要提交擔保人（子女）的出生公證嗎？
-You need to provide your birth cerrtificate to prove your blood relationship with your parents for the I-130, not the I-485. You do not need to provide your personal marriage ceritificate. Your father needs to provide his marriage certificate for the I-130 and I-485, but your mother does not need to provide it.
