My husband and I found that out when we were researching adoption.
We ended up adopting a 5-year-old from a Russian orphanage because
(1) We didn't have to go through our County and State Foster System as precondition to adoption --- which we couldn't stomach.
(2) Adopting from Russia, there was no possibility of a birthmother or birthfather making a surprise appearance and trying to bollix things up with some belated legal complication.
(3) There was no question of "open adoption" -- the requirement to be open to involving the birthmother in terms of identifying contact information or ongoing relationship, if she wants that.
Many people don't realize that adoption in the US can be tied up in a hundred legal and regulatory knots.
Not only that: I'm amazed at the people who can't distinguish between cheap, photo-op, hypocritical "virtue-signalling," and genuine "virtue", which is where you engage quietly and sincerely, act generously, and pay up personally.
They are concern trolls hell-bent on finding any reason, no matter how absurd, bigoted or sexist, to whip up opposition to Barrett.
They will fail. Yuugely.
We once looked at adopting while in New Mexico. My wife had just given birth. The lady running the classes pulled us aside and recommended we not pursue it. Why? Because many of the kids available would be 7-8 years old, been sexually abused, and she said the baby would be at risk. She herself had adopted 3 kinds, but said there were some “difficult times” preventing abuse.
We looked in to it later, in California. The woman running the local program told us since we were military, we couldn’t offer a permanent home. We were “too transient” to adopt! Pretty sure she was lying, but it wasn’t worth a legal fight.
