父母4月份在中國期間收到綠卡，下周要持有效返美證回來，我在幫他們review需要的材料。
1，從現在起，他們填表，country of residence (海關申報表上有該項）就填US，對嗎？
-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，他們入關時應走居民通道，對嗎？
-Fine.
謝謝8老師一路回答問題。
