As far as international adoption there are no federal laws prohibiting lesbian, gay, bisexual, transgender, and intersex (LGBTI) people and couples from adopting. That said, international adoptions must also adhere to the laws of the country from which the parents wish to adopt, which is sometimes problematic.
As for domestic adoption, at one time, states had their own laws regarding LGBTI adoption, with some prohibiting it. A Supreme Court decision handed down on June 26, 2017 changed this. All states are now legally required to treat LGBTI individuals and couples the same as heterosexual couples when it comes to adoption.
