You can easily stay and settle in Turkey. The important point is that your type of residence should match the goals you have to migrate so that you can reach your goal.
In general, staying in Turkey is done in 4 different ways:
1. Tourist Residency
The easiest type of residency in Turkey is to purchase or rent a house after entering Turkey. You can also renew it after you have completed your stay.
In this type of residency, you are allowed to enter into the country until the end of the stay.
The advantages and benefits of tourist residency are as follow: opening a bank account, register for the water, electricity, gas, the internet for the house you live in.
The other advantage is that if a foreigner uses this type of residency for 5 years and does not stay out of Turkey for more than one month each year, he/she can apply for a Turkish passport.
2. Academic Residence
In this type of residency, the person should be approved by one of the centers under the supervision of Turkish Education Department or higher education centers. If the applicant is accepted when he/she is staying in Iran, the person can receive educational visa with the letter of acceptance of one of the educational centers; then, he/she enters into Turkey and takes steps to get residency card. Obtaining permanent residency in Turkey is required to have a residence permit (working residency) of 5 years, but in the case of academic residency, you need to spend half of this time.
3. Working residency
This type of residency takes place after being employed in a Turkish company and being insured. In order to obtain working residency, you can take action inside and outside Turkey:
Working residency from Turkey: in this type of residency, the applicant first receives the lease or title deeds (ownership document), and then, apply for tourist residency. Upon presentation of employment documents, he/she converts his/her residency to working one. This method of working residency is called acting from inside.
Working residency outside of Turkey: this method is more relevant to those who intend to begin a business or run a company in Turkey. In this type, you must employ 5 Turks at your company and for every 5 Turkish people, you can get working permit for one foreign person. The second condition is that the company should invest about 100.000 lira. The third condition is that the salary for a foreigner should be one and a half times the minimum wage in Turkey.
4. Residency by marriage
In this type of residency, you will receive a passport after marrying to a Turk person passing 3 years from the usual 5 years. In this type of residency, a great deal of sensitivity is taken by the Turkish government. During these three years, the marriage is examined in various ways and in the case of being primitive, the residency will not be granted to the applicant.
