Hi guys, I got my GC in EB2 category through company sponsorship. I worked for sponsoring company for more than four years now. I am getting offer to work at the client side now and job responsibility and position would remain the same. ( It has been 2 months since I got my GC)  Some immigration sites suggest to remain with sponsor for 6-12 months after getting GC.However there is no definite rule as to how long one should stay with GC sponsoring company ( I have no bad intention towards my sponsor nor he has towards me. Employer says I can change employer - no problem at all). If any of you or person you know have come across some situation because of premature employer change after getting GC like getting questioned at POE, questioned during naturalization process (getting citizenship) etc...would like to know your experience.. Thanks a lot..
