Form I-864P
如果family income足够要求的话(即使自己现在无业)是不是就不用joint-sponsor?
-Right.
2: 需要joint-sponsor的话 spouse 应该没有问题对吗?
-If your spouse has eough income (belongs to family income), then you don't need a joint sponsor if your spouse agrees you to use his income for your parents' green card application. You file I-864 and your spouse files I-864A with your I-864 in this case.
