我的EB1，140在November 19, 2007批了，I485 received at April 12, 2007。我老婆现在在国内，公司律师说必须在我I485批准之前递I-824否则就不能用的priority date必须用，wait for her priority date as the spouse of a LPR (you) to become current。这对吗？下面是律师的原信，我现在是用EAD和AP。我应该怎么办？现在就递I-824吗？谢谢！
If your LPR status is granted before then, she will not be able to use your priority status and will instead have to wait for her priority date as the spouse of a LPR (you) to become current. In other words, you should either file an I-824 immediately or try to get her here sooner.
