8大師，以上是你的回答，謝謝你的耐心回答，本人對這方麵接觸太少時間太短，而我在國內還有工作。所以我還想問問：
一、如果我不能在我丈夫得到綠卡前持H4簽證及時趕回美國，這是很有可能的，因為綠卡寄出時並不會通知，當收到時才知道對不？我就不能持H4來美。那我是不是也不能再以任何其他方式進入美國，如B簽證？
-It is very difficult to get the B2 visa due to your immigration intent (I-485 filing). So, you had better apply for the Advanced parole (AP) with the I-485 filing and then, wait for the AP approval and use it to travel to China.
二、如果我不能按移民局要求的時間去打指模，我是不是還可以另要求時間？
-Yes.
三、我四年來大部分時間在美國，可這次時間在美國等的時間太長，我還在國內有工作，再兩年就可以申請退休，我的這種情況，是不是更適合I-824？
-Yes, but this will take more time to get the immigration visa (green card).
如果這樣大概比I-485有什麽麻煩呢？
-No 麻煩, but it take more time. USCIS will not process the I-824 until your spouse get the green card and also, it will take about one year for you to get the immigration visa after your spouse gets the immigration visa using consular processing.
期間我可以來美接親嗎？
-difficult due to immigration intent after your spouse gets his green card.
三、聽說有人遞交I-485後移民局會要求麵談？
-Normally no 麵談 for EB I-485.
那麽一般是什麽情況下會要求麵談呢？
-In some cases, there will be interview and hard to say why.
麵談時如果英文很差會不會有中文交談？
-You need to ask a friend to be interpretor.
