1. 想跟老师您再确认一下,12月绿卡满5年,我要是这个月(10月)材料准备好的话,就可以递交了,是吗?
-Yes.
2. 为父母办绿卡期间,他们可以合法留在美国直到拿到绿卡吗?
-Yes as long as they file -485. Even if they illegally stay before filing I-485, it will not affect their green card application.
3. 如果这期间必须回国,再来的话,如果签证过期,签证会有麻烦吗?还是说,最好留在美国,直到拿到绿卡?
-They have to apply for advance parole (AP) to travel by filing I-131 with I-485, then use the AP to travel after they apply for green card. No more B-2 visa.
谢谢!!
