Visa & Entry

Turkish passport holders enter Bulgaria visa-free for up to 90 days within any 180-day period. No advance application is needed. You can enter with a passport or a Turkish national ID card. Bulgaria shares a land border with Turkey, and the Kapikule-Kapitan Andreevo crossing is one of the busiest border points in the region. At Sofia Airport (SOF) or the land borders, immigration stamps you in quickly.

Bulgaria joined the Schengen area for air and sea borders in March 2024, with full land border integration expected later. The 90-day visa-free stay for Turkish nationals is based on a bilateral agreement and EU rules. For stays beyond 90 days, apply for a residence permit at the Bulgarian Immigration Directorate. Bulgaria has a Turkish-speaking minority of roughly 600,000 people, concentrated in the Rhodope Mountains, Kardzhali, and Shumen areas.

Direct flights from Istanbul (IST or SAW) to Sofia run about 1 hour 15 minutes on Turkish Airlines, Pegasus Airlines, and Bulgaria Air. By road, Istanbul to Sofia takes about 5 hours via the E80 highway. Bulgaria uses the Bulgarian lev (BGN), pegged to the euro at 1.96 BGN per EUR 1, trading at roughly 0.05 BGN per TRY 1. Card payments work at hotels, restaurants, and shops in Sofia and tourist areas. The Sofia Metro costs BGN 1.60 per ride (about TRY 32). Restaurants in Sofia are affordable by European standards: a main course costs BGN 12 to BGN 25 (TRY 240 to TRY 500).
