I'm not sure where exactly to post this, but I have a problem that I hope someone will be able to help me with.
My sister's son is a bright young boy who was attending a selective academy in Aus and generally doing very well. Until a few years into hitting the teenage years when he started going completely off the rails. The relationship with his parents seem to have broken down completely, he seems to just live there without any respect for them or their rules (i.e. he stays out all night when he wants to, has assaulted both parents on occasion etc.). He has been expelled from his school for poor attendance, after several attempts by the school to get him to attend. The school agrees that he is one of their brightest pupils. He then attended a state school for awhile but was kicked out from there too (I didn't even know state schools could do that) for the same reason. My sister and her husband are at their wit's end about him. He is only this way with his parents, they sent him for two months to our aunt's (just for a change of scenery and for him to collect this thoughts and come back) and he was fine. Did chores around the house, respected the hosts etc. and seemed genuinely happy. However they live in a third world country, so he doesn't want to live (longterm) or study there .
My sister has asked me if I could have him for a year or two, as it's them he seems to be unable to live with. Is this possible? Will I be able to get a visa for him where he could live and go to school in the UK? He just turned 16 last week.
