Pjiang, Thank you very much!!! There are a few more things,

I would like to ask:
1) shall I wait for the approval of I824 before I move back to China?
2) which address shall I give in I 824? current address in US orfuture address in China?
3)I need to file the address change before I move to china, am I right?
4)does it worth me to renew my AP before I file I 824? It seems the AP is still valid after I give up I 485?
5)After I move back to China,Will the CP status affect my application for business or visiting visa for US?


Thanks a lot!
