By the way, as I said before, even if your child's I-485 is denied, she still can file a new I-485 based on your wife approved I-485 later.
Suppose we don't do anything now and just wait. If me and my wife's 485 approved and my daughter's I-485 denied? in this situatio, will my duaghter be out of status (since her H4 is dependent on my H1-B and my H1-B will dispear once my 485 get approved), If her H4 expired, how can we file her a new 485? please explain a little bit.
Thanks again for your help!
