I was wondering if I was wishing to visit Turkey every month for 2 weeks continuously...would I still have to apply for a residency permit?

I understand you can reside in Turkey for a maximum of 90 days.

As I would be leaving the country after 2 weeks and then returning. Would I be 'covered' under the above i.e 90 days.

Thanks

Depends on your nationality.

British and americans get 90 day multi-entry visas at the airport for a small amount of money at the airport.

so you can go and come as many times as you like within the 90 days without buying another visa.

If you are a different nationality the rules may be diferent for you...
