No. A 22 year old is an adult and, as such, is too old to be adopted.
Yes you can adopt your niece but you would have to get in the same country and it would be a little weird but if you need to or want to that would be a great idea hope you have fun
Depends what country she is in. When you as an American adopt an adult, the adoptee does not become an American citizen. It also varies between states. Some are very restricted when it comes to adult adoption and apparently Michigan is the worst. the best thing you can do is to consult a lawyer.
Niece is already the answer - A male niece is a nephew.
Male niece is female
Your Aunt's niece is you (if you are female), your sister, or your First Cousin.
No, if you are married you cannot adopt unless both of you are willing to adopt.
Your sister's daughter is your niece. If you are a woman, you are your niece's aunt; if you are a man, you are your niece's uncle. Your sister's son is your nephew.
well you should be able to but if not then just do it secretly until you can but if you don't want to do that then have you mom adopt her under your name
Alphonse Frankenstein adopts his niece, Elizabeth Lavenza, when sister died and her husband offered Alphonse to adopt their daughter, Elizabeth.
You are her niece or nephew (niece if female, nephew if male) and she is your aunt.
Yes, your sister's daughter is your niece and you are her aunt (if you are female) or her uncle( if you are male).
That will depend on the local laws. In some places you cannot adopt until you are 21. Others may allow you to be the guardian until you turn 21.
