Little Details

Hi! Just heard about this community and am very excited to join in.

I have two questions related to adoption by American parents. I've tried to do internet searches but am not getting the exact desired info. If you have sources I can go and read to get the information, that would be great as well!

1. In the first situation, a pregnant British citizen comes to the US, gives birth in the US, and then decides they want their American friend to adopt the baby. The British person will give up all parenting rights. The baby will be a US citizen given they were born here. Are there any special hoops the adopting parent will have to go through because the birth parent is not a US citizen, or is it the typical process of newborn adoption? Is there anything the British person needs to file or report in the UK since the baby is not going back to the UK? I'm thinking not but just checking.

2. In the second situation, an American wants to take in an orphaned child who is fleeing another country due to an active war. Is there any path to adoption? Sources I've seen say Americans can only foster refugees, not adopt. The child knows for sure that their parents are dead (one died before the war, one died during). This is not exactly a cross-cultural case, as the country at war is England (this is modern-day but AU obviously). It's a little bit cross-cultural, as the American is Jewish and the English child is probably affiliated with Church of England, but I don't think that will really matter.
