-Your father has to apply for immigration visa in China, and your mother can file I-485 in US. There are two different cases. You can file two I-130 at the same time, respectively, for your parents.
一起交的話,交到哪個CENTER?
-Check this website (please note that the addresses for two I-130 are different if your mother wants to file I-485 together with the I-130):

另外問下我爸在國內,如何通知他打指紋,做體檢?要去哪裏做?一定是廣州嗎?家在上海。
多謝了。
