a question about H4 and I485

[joyo]

I filed H4 (F1 to H4) in Oct, 2004. The notice says it takes 100-150 days for processing. So far, I have not heard anything from INS. We recently are planning to file our 485. (My wife's I-140 filed in May, 2004). My question is,

1. My 485 application would effect my H4 application, even cause H4 would be denied.

2. Should I file 485 until H4 has been approved.

Thanks for your response
