急！請教皮匠和各位大師:Will his I-485 application be invalid and he needs t

My statuses: I-140 approved in 2007; I-485 pending and fingerprinting with my son and wife in 2007 in USA. My son is a senior college student, F1 holder and Canadian. This year he will go to UK for a special study project which belongs to the college study program. My questions: 1) Will his I-485 application be invalid and he needs to re-apply I-485 again if my son leaves USA to UK? 2) How to solve the problem, filing the I-131?

Thanks,

naomama
