请读下面的规定。可不可以这样理解：假如我有一个孩子，１８岁，今年由美国朋友收养。明年可以通过养父母办身份？
Who is an Adopted Child Under the Immediate Relative Process?
Under this process, an adopted child is considered, for immigration purposes, to be the child (or adult son or daughter) of the adopting parent if:
- The parent adopted the child before his or her 16th birthday (or before the 18th birthday under certain circumstances as described below). You submit evidence of a full and final adoption
AND
- The parent had legal and physical custody of the child for at least two years while the child was a minor
- The legal custody must have been the result of a formal grant of custody from a court or other governmental entity
- The custody and residence requirement may be met by custody and residence that preceded the adoption
- The two years custody and residence requirements are waived for certain abused children
