我是今年7月中旬給我父母申請了綠卡。priority date是7月22。10月26我們收到信說可能不需要麵試了，但是由於人多，所以他們拿到綠卡的時間可能要延長。
我媽要1月中旬回國。她想要5月中旬才回來。我再想這之間如果綠卡下來了，我是需要寄給我媽還是不寄？如果不寄她仍然需要持AP入境，如果有綠卡還持AP，請問會有問題嗎？
-Just use the AP to come back, but they need to tell the IO at the port of entry that their I-485 was approved during their travel in China. If your parents do not know English, you may write a letter for them to explain it to the IO, thus your parents just present the letter to the IO when they enter US.
還有有些擔心麵試。信上沒有說一定不要麵試，隻是說很可能不要，這樣會突然被要求麵試嗎？萬分感激
-Then, you may bring the appointment notice to the local USCIS Office to ask the IO to reschedule it.
