Residence Rules ?
You will be treated as resident in Turkey if you have your permanent domicile in Turkey, or if you spend more than six months in Turkey in a calendar year. Businessmen, scientists, journalists, scholars, officials and other such persons who come to Turkey for a specific and temporary job are not considered to have settled in Turkey even if they spend longer than six months there.
Residence permits are usually valid for two years but are renewable for an unspecified number of times.
