coming to here USA is the hard part...going back...now that is no problem....seen a lot of people who stayed illegally and returned back home with no hassle......,get your ticket and off you go....kiss goodbye to America coz you're never comming back...so think hard my friend..may be try for asylum...but if you have had it here then going back will be the right thing for you......dont be worried...you are leaving not arriving. good luck
