Bismillah I would either go to Canada, Australia, Newzeland, Turkey, Malaysia and UK& US being the last on the list. One key point is if you want to safeguard your deen, it is almost wajib to 1.connect yourself to a seassoned reputable scholar from any of islamic seminary and 2.be involved in dawah organisation that focues on the self betterment and the wider community. 3.For some I would even add a shaikh of Tassawuf with grounded in shariah. This is where most people go wrong by ignoring this steps and later on their family and deen suffers. Of all the people I have known most of their family problem is due to being apathetic to the trend outside and taking appropriate measures. It is unlikly things will go wrong if one is sincere in their venture and do not adopt a self righteous arrogant know it all attitude. As for qatar or UAE, these countries are fine for medium term stay. We can't become citizen of these countries and I agree with this policy unless you want these country to follow others in loss of their control over their countries. One can do whatever you want. If you want relegious knowledge, you have to work a bit harder unlike in the west. The above mentioned point still need to be adhered to as much as possible. Allahualam
