However, besides being a home to a huge tourism industry Istanbul makes also a very popular destination for expats. Ever since it was built, as a city located on two continents it has been a home for a huge variety of cultures as well. With more and more expats living in Istanbul, this tradition remains until today. The strong economic growth it has while maintaining the low costs of living makes it particularly attractive for those coming from countries where the costs of living are higher.
The weather in Istanbul makes it particularly attractive for those seeking to settle in a warmer part of the world. Beautiful weather also makes one of the top three reasons why expats choose to move to Istanbul or Turkey in general.
Being a liberal city, Istanbul will make you feel like at home. There are a lot of events, concerts and other activities going on and thus you will never feel bored living there. And although it's not easy to find a job in Turkey as an expat, especially without speaking Turkish, many native English speakers find jobs such as teaching English and start learning Turkish on the side. Adapting in this friendly environment is not that hard is it may seem at first thought of being new there.
In addition, due to the fact that a lot of expats are living there you can find many English speaking communities, most likely some of them are even your countryman willing to meet and spend time together.
