我下周就会宣誓成为美国公民。准备给我父母办亲属移民。有一个问题是，到底我需不需要提供父母的结婚证书。 我看了Pjiang的130 instruction, 说不用提供结婚证书，只要有我的出生公证就行了。但是CIS的网上却说：A father: Submit a copy of your birth certificate showing the names of both parents. Also give a copy of your parents' marriage certificate establishing that your father was married to your mother before you were born, and copies of documents showing that any prior marriages of either your father or mother were legally terminated.
主要是我父母几年前搬家把结婚证丢了，现在要重办一个很麻烦，也耽误时间。他们在民政局办了一个结婚状况证明，不知能不能行。
非常感谢您的帮助。
