回複：I-485file上去後的結婚問題

As long as you keep H1, you wife is eligible to get H4. But she has to pass the H4 visa interview in US consulate first.
After arrival, she won't be able to submit I-485 until PD current, but your I-485 shouldn't get approved before PD current either. So she needs to be ready to file I-485 the first day PD becomes current to avoid receipt after your I-485 approved. This is the easy part.

The hard part is that she needs to be in H4, which means she needs you to be in H1 for the next several years (You may need to extend beyond 6 years), or she needs to find her own F1, H1, etc before filing I-485.
