1)我的W2 是足够的,但是944 既然我放进去了,是不是我老婆孩子也得放进去?
-Not need because I-944 is your mom's. But Your kids need to be counted into your household size in I-864 if your spouse has enough income for herself living.
还是说可以household 只填我母亲和我?-Yes.
2)如果只用864,不用 864A, 那意味么我一个人就可以sponser (事实也是这样) 但是您的意思是可以放 joint tax report?
-Provide the copy of joint tax return, but you only can put your personal income in I-864 and provide the copy of your personal W2.
有没有规定放 joint tax 就必须配偶填 864A? -No.
