If you convert 45k to US dollars and you earn almost the same amount, then you better stay in the US. If not, don't hesitate, move to Qatar. I have nothing against Qatar because the locals are now very adaptable people especially if you work in a well sought company. In fact you might probably feel that other arabs are more up to themselves. The way people drive there is crazy though. No discipline and road rage is massive! I had lived in Qatar for x amount of years so I know what it's like. I will come back definitely...my passive lifestyle suits me to be there. good luck!
