If you are a native-born or naturalized U.S. citizen, you can sponsor a married child. You can sponsor your foreign born child for lawful permanent residence (i.e. a green card) if he/she is your biological child, stepchild, or adopted child. Your child’s spouse and children who are unmarried and under the age of 21 can immigrate to the United States with your son or daughter.
- The stepparent-stepchild relationship must be formed prior to the child’s 18th birthday to be considered a child under U.S. immigration law. The immigrant visa petition can be filed after the child’s 18th birthday.
- The child must be adopted prior to his/her 16th birthday to be considered a child under U.S. immigration law. A limited exception applies when siblings are adopted. In such circumstances, if a child is adopted prior to his/her 16th birthday, his/her siblings will also be considered a child under U.S. immigration law so as he/she is under the age of 18 at the time of the adoption.
