Just to want to thank all the people who help me here, especially LoveWind, WorthIt. They are so nice. I sincerely appreciate their encouragement and help. I learned a lot here. Thank you all for keeping this post a wonderful place. here is some information about my application.

Approved on Jan 18, 2006.
Did it by a lawyer.
We went back China during Christmas time, applied H-1B visa and H-4 visa in Beijing, even though we have AP on hand. No problem at all to get the visa. Just need to take two hours for the whole application. I didn't see anybody with H visa denied or checked. A lot of students got F-1 visa too. Maybe the officer were in good mood since it was close to Christmas time.
Anyway, best luck for you all and happy Chinese new year!
