請教：485 材料在local office，現在要換工作去外州

EB2 NIW PD 6/2003, approved 7/2005
485 RD 9/2005, transferred to local office 11/07

I received layoff notice and job hunting with EAD now. Most likely I cannot stay in my current state. What should I do with my 485? Can I leave it in the local office or should I ask them to transfer back to NSC?

xiaobaitu, pjiang... your kind opinion is appreciated.
