8大师，以上是你的回答，谢谢你的耐心回答，本人对这方面接触太少时间太短，而我在国内还有工作。所以我还想问问：
一、如果我不能在我丈夫得到绿卡前持H4签证及时赶回美国，这是很有可能的，因为绿卡寄出时并不会通知，当收到时才知道对不？我就不能持H4来美。那我是不是也不能再以任何其他方式进入美国，如B签证？
-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时间去打指模，我是不是还可以另要求时间？
-Yes.
三、我四年来大部分时间在美国，可这次时间在美国等的时间太长，我还在国内有工作，再两年就可以申请退休，我的这种情况，是不是更适合I-824？
-Yes, but this will take more time to get the immigration visa (green card).
如果这样大概比I-485有什么麻烦呢？
-No 麻烦, 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.
期间我可以来美接亲吗？
-difficult due to immigration intent after your spouse gets his green card.
三、听说有人递交I-485后移民局会要求面谈？
-Normally no 面谈 for EB I-485.
那么一般是什么情况下会要求面谈呢？
-In some cases, there will be interview and hard to say why.
面谈时如果英文很差会不会有中文交谈？
-You need to ask a friend to be interpretor.
