Types of Visas to Turkey, and Legalities

Generally there are two types of tourist visas - a single entry visa (called Tek giris) and a multiple entry visa (called Muteaddit giris). A single entry visa allows a one-time entry into Turkey and once you leave the country (irrespective of your length of staying) you need to obtain a separate visa to re-enter Turkey. A multiple entry visa, on the other hand permits multiple entry into the country, within the span of its validity without incurring any additional cost. Majority of the visitors however, require a single entry visa. Only if you have a plan to enter and leave Turkey 4-5 times in a span of three months, you can go for a "Muteaddit giris".

The visa application form entails two important sections - occupation and purpose of visit. As per legality, a general tourist visa does not permit working or studying in Turkey. For such purposes, you need a work/study visa as well as a residence permit.

If you are an ordinary passport holder, you cannot indulge in any diplomatic, military or official business in Turkey. For such purposes, your visa needs to be stamped with the words "official passport".

Similarly, if you want to shoot documentary films, go for an archaeological excavation or conduct a research, you have to apply for prior special permission from the Turkish authority.

Visa requirements for truck drivers are also separate.
