鄰居老伯，幾年前由孩子辦理的綠卡，但是孩子不給他的結婚20年的老伴（後媽）辦理，
-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.
聽說隻能公民才能給老伴辦理綠卡，隻好拚命學英語，想考上公民給老伴辦理，隻是年老，進展很差，感到無望。
讓我問問大師，綠卡人能夠給老伴辦理綠卡嗎？
-Yes. But it may take about 5 years for her to get the immigration visa in China.
需要如何辦理？
-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?
請大師指導一下，謝謝！
