父母4月份在中国期间收到绿卡，下周要持有效返美证回来，我在帮他们review需要的材料。
1，从现在起，他们填表，country of residence (海关申报表上有该项）就填US，对吗？
-Right. If your parents do not know English, you had better write a letter (use your parents' names) to address that their I-485 have been approved during their travel in China, and your parents just present this letter to the IO at the port of entry when they enter US.
2，他们入关时应走居民通道，对吗？
-Fine.
谢谢8老师一路回答问题。
