Obtaining Bulgarian citizenship on the basis of Bulgarian descent is quite straightforward. The only significant drawback of this route is that it is available only to those who have Bulgarian ancestors (Bulgarian citizens) or adoptive parents who are Bulgarian citizens.

To obtain citizenship on the basis of Art. 15 of the Bulgarian Citizenship Act (by descent), you must have at least one parent who is Bulgarian by nationality (or prove his or her Bulgarian descent through his or her ancestors) or a Bulgarian citizen (including a deceased one), or have been adopted by a Bulgarian citizen.
Documents confirming entitlement on the ground specified in Art. 15 of the Citizenship Act:
— Persons of Bulgarian descent submit a certificate of Bulgarian descent issued by the State Agency for Bulgarians Abroad. It is recommended that the naturalisation application be accompanied by the documents on the basis of which the applicant’s Bulgarian descent was established and the certificate of Bulgarian descent was issued;
— Persons adopted by Bulgarians submit documents on full adoption and official confirmation of the adoptive parent’s Bulgarian citizenship;
— Children of Bulgarian citizens submit documents on their parents’ Bulgarian citizenship (or confirming that the parent died as a Bulgarian citizen).
All documentation must be translated into Bulgarian and certified in accordance with the applicable rules.
The application together with the package of documents is submitted in person to the Ministry of Justice and registered with the Bulgarian Citizenship Directorate. After registration, the applicant is informed of the date and time of the interview, which is conducted in Bulgarian.
