Part1,24.what is your current immigration status (if it has changed since your arrival)? 应该填什么?-Your parents' current status such as B2 visitor, etc.
我父母一直是B2没有变更过状态,这里是不是应该空着不填?还是填B2?
-Eitheris fine.
131表格有个问题想请教,Part4 information about your proposed travel,1a. purpose of the trip 和1b, the country you intend to visit 需要填写吗?(我是帮父母申请绿卡)
-Yes. Just say something like visit relatives and friends in China.
