Oikonomakis Law Firm
Sofia, Bulgaria
OIKONOMAKIS LAW has advised on cross-border immigration and investment matters since 1997 and maintains an office in Sofia alongside offices across Europe, the Middle East, Asia and Africa.
Our Sofia team advises on Bulgarian investor residence, including permanent residence by investment under the Foreigners in the Republic of Bulgaria Act, the qualifying fund routes, source-of-funds and anti-money-laundering documentation, the type D visa and permanent residence procedure, and applications for family members. We advise on the conditions under which permanent residence may later found an application for naturalisation under the ordinary provisions of the Bulgarian Citizenship Act. Bulgaria's former accelerated citizenship-by-investment programme was abolished in 2022 and no route exists by which an investment produces citizenship directly.
Beyond Bulgaria, we act on European residence-by-investment matters across the jurisdictions in which the firm operates, on international investor immigration generally, and on the corporate, tax and structuring questions that sit alongside a residence application rather than separately from it.
The office also handles company formation, corporate restructuring, commercial contracts, regulatory compliance and cross-border transactions involving Bulgarian entities, frequently for clients using Bulgaria as a base within the European Union.
