Thanks Riddle/Jharke/Abi for your sources and information, i really appreciate your input to my questions. Just kind of confused - i bet all of us are on the same boat for these kinds of situations - i wish we have dual citizen ship so that we dont give up what we achieved here for so long years being far from our family/friends and home/country.. i wish you all the best whomever had a similar kind of dilemma on whether to stay here or go back for good.
