Questions for AP and EAD renew 请教指点2007-05-04 19:50:35

my AP and EAD will expire in December 2007. I must renew them for next year. How to renew them?

I will go to china in June and return in the end of August.
Can I renew them when I come back from china?
Do I need to stay in USA for renew them?
Thanks
