Dear Mr. Peralta,
Thank you for posting your request on History Hub!
The Federal Government does not ordinarily create or maintain birth, adoption, death, marriage or divorce records. Such records are made and kept by State and local governments rather than the National Archives. We suggest that you review the FamilySearch Research wiki for United States Adoption Research and Obtaining Birth and/or Adoption Records to begin your research.
We hope this is helpful. Best of luck with your research!
