Couple of options for domestic adoptions:
1. Have a ton of money - No problems
2, If #1 presents a problem, go with county / state agency. Be prepared to have your life / habits / beliefs examined and also to serve as foster parents for a time.
3. If #2 presents a problem, such as some reticence to open your whole life to the state or you hestitate to bring foster children into your home, foreign adoption becomes a relatively attractive option.
