WHAT HAPPENS IF YOU WORK IN TURKEY WITHOUT A WORK PERMIT?
If would like to work in Turkey either you need to be a Turkish Citizen or you need to have a work permit. Working without a work permit is an unlawful act and the worst result is deportation. Also you and the company you work for will be fined.
If you are on a Tourist visa in Turkey you should not work at all, because in that case you will be deported from Turkey and a year restriction will be placed on your visa. That means you cannot enter this country for a year. This duration can be extended if you do not pay the fine which will be issued after the deportation.
If you have a residency and if you get caught while you are working without a work permit, you will not deported strait away.
