If you graduate and qualify as a pharmacist in the USA, that in itself doesn't give you the right to practice in Turkey, you'll need to qualify there again (which could be just a formality, but more likely they'll make you undertake some study to familiarise yourself with the local regulations etc.).
You won't earn anywhere near as much as a pharmacist in Turkey as you would in the USA. My guess is you need to at least half that figure, maybe cut it by two-thirds. Of course living costs will be lower, but not in proportion (especially if you want to settle in Istanbul, which is a very expensive place to live).
You'll find it difficult to get a work permit, because a) you're not qualified to practice in Turkey, b) even if you were, it's not like there's a shortage of pharmacists in the country, and c) you don't speak the language so you'll find it difficult getting an employer interested enough to sponsor you through the work permit & visa process.
I fully agree with you that Turkey is a wonderful and exciting place, the people are friendly, food is great, etc. Although I'm not entirely sure I agree that they're quite as liberal as you seem to think; some are, but some (the majority?) aren't, at least not if the politics of the last ten years or more are anything to go by...
Why Turkey of all places? If I were you and had the opportunity, I would consider a more civilized/developed country.
Yea Turkey is cool; perfect climate, sea, food, history and all. But we got huge problems caused by copious amount of unconscious bumpkins spread all around the country.
Still there are 'green zones' where many modern people live together like Kadikoy, Cankaya, Besiktas, Bakirkoy, Karsiyaka and such. Those could indeed be wonderful places to live in, albeit expensive.
Turkish people are Turks, not Arabs.
If you don't speak Turkish fluently, you won't blend in there at all. And you are unlikely to be working in pharmacy ....
My suggestion would be to find how long you can stay there as a tourist, and see if you would like living there first.
gel burada ?evirmen olarak ?al?? :D ?ok turist arap var bo?ver eczal??? falan.
