From uscis website ( Tip for filing petition/application), for I-130, it said "submit both the petitioner’s and beneficiary’s birth certificates with English translations (if needed)", but in the instruction for form I-130, it doesn't say anything about birth certificate..Anybody knows the right way to do this? My husband doesn't have the birth certificate (borned outside US but will be citizenship soon), can she use the naturalization certificate instead? Anyone pls clarify for me..Thanks
