父母多年前离婚，我可以给国内的父母亲和继母都办绿卡吗？ 可以先给母亲单独办，然后再给父亲继母一起办吗？先谢谢了！
-If your father married your step mother before you turned 18 years old, then you can sponsor your step mother's green card application. Otherwise, your step mother cannot immigrate into US together with your father. Only one way is that your father sponsor her after your father gets the green card.
