The person is now an adult and therefore an adoption could not be "reversed' or expunged. The adult can change his or her name back to their birth name or to any other they might choose.
yes, see adult adoption.
I contacted the adoption agency in the town where I was adopted from. You could be assigned a case manager who will work with you.
An adult can definitely adopt an adult. This can prove to be one of the easiest adoptions. Simply because the adult being adopted would need no permission from his or her biological parents as long as he is over the age of 18. If that adult is married, is the only permission needed. The spouse will need to give his/her permission for you to be adopted. I have heard of several forms of adoption but adult adoption I've heard to be the easiest.
No. Anyone adopted over the age of 16 does not automatically get US citizenship. Sorry.
Cannot without official adoption.
No. A person can not be adopted once they reach the age of 18 in the UK.

Unless specifically addressed in the motion for adoption, than yes.
Unless they choose you there is no way. And for you to be adopted your parents must have given up their parental rights and put you up for adoption. Most couples wants babies though or at least toddlers. Teens rarely get adopted. If you are an adult you must first have a bond with the adoptive parents or the court will not allow it. And some think they become American citizen when adopted as adults but they do not.
No. Adoption severs all legal connections between the two. However, the adopted child is entitled to make a claim on their adopted father's estate.

Generally yes. The laws on this vary from state to state. Most states in the USA allow for this; it's generally called "Adult adoption"
