邻居老伯，几年前由孩子办理的绿卡，但是孩子不给他的结婚20年的老伴（后妈）办理，
-Their marriage had to occur before his child turned 18 years old so that his child can be qualified to sponsor his spouse (child's step-mother) green card application.
听说只能公民才能给老伴办理绿卡，只好拼命学英语，想考上公民给老伴办理，只是年老，进展很差，感到无望。
让我问问大师，绿卡人能够给老伴办理绿卡吗？
-Yes. But it may take about 5 years for her to get the immigration visa in China.
需要如何办理？
-File I-130 with the same procedure as the US citizen sponsor does. But the problem is that he has to have the financial ability to support his spouse's GC application. Otherwise, his kid has to be the co-sponsor. Is his kid want to be the co-sponsor if he has no enough income/financial ability?
请大师指导一下，谢谢！
