Hi all,
My wife and I are looking to adopt her niece's daughter, who lives in Thailand. My wife is from Thailand and has her US Green card and I am an American Citizen. We live in the US. My wife's niece was newly married and shortly after the birth of their lovely daughter her husband tragically passed away from cancer. Their daughter is one and a half years old now. The niece is quite young and wishes to continue her education. My wife and her niece have discussed us adopting this child and taking care of her in the US. My wife and I are happy to do this and agree that it is the best for the child and mother and coincidently ,we were discussing having a child ourselves - so there is "Room at the Inn" so to speak both physically and mentally.
My question is what is the best way to go about getting an adoption of this sort approved and through the system in Thailand and the US? I am willing to spend a great deal of time and effort to accomplish this, and will also spare no expense if it makes the process easier. Any help would be most appreciated by all parties involved here.
Thank You for your time.

PS my wife and I are happy to answer any questions that adoptive parents may have on Thai culture etc
