help?

[StephanieM 60]

I posted about this before but remain confused. My husband wants to bring his father and was born out of wedlock. His father is on his birth certificate. This is what I read on a guide (below), so what does this mean, can I just send my husband's birth certificate and thats it? And then maybe expect a DNA test? Or should I send anything else up front to avoid RFE, help?

My father. I was born out of wedlock and legitimated:

If you are applying to bring your father to the United States to live and you were born out of wedlock and were legitimated by your father before your 18th birthday and while you were unmarried, you must file the following with the U.S. Citizenship and Immigration Services (please note: if you have been legally adopted, you may not petition for your birth parent):

Form I-130, Petition for Alien Relative (if you are filing for both parents, you must file a separate petition for each parent)
A copy of your birth certificate showing your name
If you were not born in the U.S., a copy of either
Your Certificate of Naturalization or Citizenship or
Your U.S. passport
Evidence that you were legitimated before your 18th birthday through
A. the marriage of your birth parents, or
B. the laws of the state or country where you live, or
C. the laws of the state or country where your father lives
If anyone’s name has been legally changed (differs from the name on his or her birth certificate), evidence of the name change must be provided.
