Bulgarian nationality law

Bulgarian nationality law is governed by the Constitution of Bulgaria (article 25 and 26) of 1991 and the citizenship law of 1999 (with changes made in various years through to 2009).

It is mainly based on jus sanguinis; however, it is possible to obtain citizenship after 10 years of residence in Bulgaria. Naturalisation is available on the basis of residence in certain types of status; marriage or on the basis of origin or at the discretion of the government of Bulgaria to persons of merit. The Bulgarian Ministry of Justice is in charge of processing citizenship applications.

Every Bulgarian citizen is also a citizen of the European Union.

Bulgarian citizenship can be acquired in the following ways:

Bulgaria allows its citizens to hold foreign citizenship in addition to their Bulgarian citizenship. Some countries, however, do not permit multiple citizenship e.g. adults who acquired Bulgarian and Japanese citizenship by birth must declare, to the latter's Ministry of Justice, before turning 22, which citizenship they want to keep.

Bulgarian citizens are also citizens of the European Union and thus enjoy rights of free movement and have the right to vote in elections for the European Parliament.

Visa requirements for Bulgarian citizens are administrative entry restrictions by the authorities of other states placed on citizens of Bulgaria. In 2015, Bulgarian citizens had visa-free or visa-on-arrival access to 150 countries and territories, ranking the Bulgarian passport 18th in the world according to the Visa Restrictions Index.
