Obtaining Turkish Citizenship by Birth – Jus Soli / Jus Sanguinis
Turkish citizenship can be obtained by birth or after birth.  Articles between 6 and 8 of Turkish Citizenship Law regulates the principles regarding acquisition of Citizenship by birth. In principle Jus Sanguinis principle is recognized as the basis for acquisition of citizenship by birth. Article 7 reads that ‘a child born to a married Turkish father or mother, whether in Turkey or abroad, is Turkish citizen.’ Under article 7 a child born to a Turkish mother and a foreigner father out of wedlock is accepted as Turkish citizen. On the other hand, article 7(2) puts forward that a child born of a Turkish father and foreigner mother out of wedlock acquires Turkish citizenship if the principles and procedures regarding the determination of descent are met.
Jus Soli principle is only applicable under article 8 as if a child born in Turkey but acquiring no citizenship from his/her foreigner mother or foreigner father. As per article 8(2) a child found in Turkey is deemed to have been born in Turkey unless proven otherwise.
Obtaining Turkish Citizenship After Birth
Under Turkish law, in the absence of natural link, citizenship, after birth, can be obtained by three ways; through decision of competent authority, by adoption or by right of choice.
1. Acquisition of Turkish Citizenship through Decision of Competent Authority
Through the decision of competent authority, Turkish citizenship can be acquired through four ways; naturalization, exceptional naturalization, reacquisition of Turkish citizenship, acquisition of citizenship through marriage
a. General Naturalisation
Naturalisation through the decision of competent authority requires satisfaction of certain conditions set forth under article 11 of Turkish Citizenship Law. Accordingly, foreigners with at least five years of uninterrupted residence in Turkey, who are at the age of majority and capacity to act according to their national legal system (Turkish Civil Code numbered 4721 is applicable for stateless foreigners) might be eligible for Turkish citizenship upon the satisfaction of each of the following conditions.
- have the intention of settling in Turkey and prove this intention with action,
- not have any disease that constitutes a danger to public health,
- be a person of good morals,
- speak an adequate level of Turkish,
- have an income or profession to provide for his own livelihood and those of his/her dependents in Turkey,
- not pose a threat to national security and public order.
For the purpose of article 15 (c) of the implementing Regulation, following situations are assessed as having intention continue to live in Turkey; owning immovable property in Turkey, establishing a business, investing, transferring a trade and business center to Turkey, being employed through work permit or relevant permission, or marrying a Turkish citizen, filing application to acquire Turkish citizenship as a family, having a mother, father, brother or child who has previously acquired Turkish citizenship or having studied in Turkey.
Foreigners without residence permit, or those who are staying in Turkey legally but without intention to settle in such as asylum seekers, or residence permit holders whose permits are granted for the purpose of tourism, medical treatment, studying in Turkey, accompanying children studying in Turkey or foreigners having a pending trial for any offense or convicted or imprisoned for any crime would not be considered eligible for the Turkish Citizenship.
b. Exceptional Naturalization and Jus Pecuniae: Investor Citizenship
It is for each state to decide who are their nationals. States’ sovereignty over the nationality matters commonly recognized within the scope of domestic jurisdiction, however not without reservation. States’ discretionary power limited with International law, custom and norms. State discretion over the nationality issues facilitates extraordinary naturalization clauses under nationality codes of states by providing exceptional citizenship to foreign nationals on the grounds of their exceptional contributions to societies such in the terms of economy, culture, or sport.
Turkish Republic’s first Nationality Law, Turkish Citizenship Act numbered 1312 (1928) was enabling exceptional citizenship through the decision of cabinet of executive ministers. Following, Turkish Citizenship Act numbered 403 (1964) has further clarified in a more comprehensive way, the discretion of Council of Ministers in granting exceptional citizenship. Foreigners based on value of their input in Turkey within the economic or social context or in the fields of science, technology or art, through the decision of the Council of Ministers, without considering five years legal residence in country requirement set forth for general naturalization applications has been considered eligible for exceptional citizenship. 
Boundaries of the discretionary power of executive in grating citizenship exceptionally reviewed under Law no 5901 on Turkish Citizenship (2009). Especially with the additions to the article 12 of Law no 5901 through the amendments introduced in 2016 by Law no 6735 on International Labor Force, exceptional ways of acquisition of Turkish citizenship started to cover a procedurally defined Citizenship by Investment clause as well.
Under its current regime, upon presidential decision, Turkish citizenship can be obtained exceptionally. Exceptionally, as per article 12, if there is no obstacle in terms of national security and public order, following four categories of foreigners can be granted Turkish Citizenship.
- Those persons who bring into Turkey industrial facilities or have rendered or believed to render an outstanding service in the social or economic arena or in the fields of science, technology, sports, culture or arts and regarding whom a reasoned offer is made by the relevant ministries.
- Those residence permit holders explained under article 31 (j) of Law no 6458 on Foreigners and International Protection and those turquoise card holders and their foreign spouses, their minor or dependent foreign children.
- Those whose being received into citizenship is deemed to be necessary.
- Those persons who recognized as migrants.
Discretionary power of Competent Authority in the application of article 12 is relatively more when considering previous versions of Turkish Citizenship Act.  Turkish Citizenship through the application of suitable provisions of Article 12, can be acquired by the proposal of Ministry of Interior, with the presidential approval. For the purpose of Turkish Citizenship Act, “migrant” refers to those persons, as prescribed under Law no 5543 on Habitation, who belongs to Turkish ancestry and Turkish culture who arrived in Turkey with the intention to settle in.
As per article 31(j) of Law on Foreigners and International Protection, under certain circumstances short-term residence permit can be issued for those foreigners who does not work in Turkey but will make an investment within the scope and amount that shall be determined by the President, and for their foreign spouses, his and her minor children or foreign dependent children.
Both provisions, article 12 (1) (b) of Turkish Citizenship Law and article 31(j) of Law on Foreigners and International Protection, which have been introduced by article 27 of the Law no 6735 on International Labor Force provides main pillars of Jus Pecuniae in Turkey.
As stipulated under article 12 (1) (b), a foreigner to be qualified for “Investor Citizenship” either should be considered as residence permit holder in accordance with article 31(j) of Law on Foreigners and International Protection or should be a turquoise card holder as defined under Law no 6735 on International Labor Force.
Following the significant changes in the law, on 12 Dec 2016, through the Council of Ministers decision on the amendment in the Implementing Regulation, a new subparagraph added under article 20 of the implementing regulation, to outline the conditions for obtaining citizenship through investment. With the introduction of article 20 (2), investment types and thresholds for Investment-based Turkish Citizenship has been clarified. Upon recent modification of the pre-determined investment threshold through Presidential Decree No. 106 which was published on 19 September 2018, following criteria is currently represents investment thresholds for the implementation of article 12 (1) (b).
- Proven by the Ministry of Industry and Technology to have made a minimum fixed capital investment of USD 500,000 or equivalent foreign currency or Turkish lira.

c. Reacquisition of Turkish citizenship

As per article 13 of the Turkish Citizenship Law, who had renounced Turkish citizenship through permission and who have not used ‘right of choice’ within three years  after losing citizenship due to their parents, can reacquire Turkish Citizenship without being subject to residence permit requirement. Based on article 14, on the condition that having legal residence in Turkey for three years, those who lost their citizenship pursuant to article 29, through Presidential decision and those who lost their citizenship in pursuant to article 34, through decision of Ministry of Interior can reacquire their citizenship. For the purpose of Turkish Citizenship Law, in the calculation of required uninterrupted residence permit period, periods of residence outside of Turkey should not exceed in total twelve months.
d. Citizenship for spouses of Turkish Citizens

 Unlike other ways of acquisition of Turkish Citizenship which are requiring foreigners to not pose any threat to the National Security and Public Order, Reacquisition of Turkish Citizenship as per article 13, requires not being in a position to have an obstacle to the National Security. Condition of not posing any obstacle to the Public Order is excluded deliberately in a way to facilitate the reacquisition of Turkish citizenship.
