If you legally adopted your child abroad, the adoption is valid. Still, most adoption authorities recommend as an additional safeguard that you readopt your child in the United States under the laws of your state. This will also give you readily available evidence of the validity of your child’s adoption. Some states may not permit readoption, so check locally to see if this can be done. If your child left his or her country of birth under a guardianship, not a final adoption, then you must adopt in the U.S.
