Passports and Visas
Foreign visitors from outside the European Union must possess a passport valid for at least the next 6 months. Some congress participants may require visa in order to enter Poland. Please check with your local Polish Consulate or Embassy for details regarding visa and entry requirements.
Liability
The Congress Secretariat and Organizers cannot accept liability for personal accidents, loss of belongings or damage to private property of participants and accompanying persons, either during or directly arising from the NBC 2025 & PCBBE 2025. Participants should make their own arrangements with respect to health, travel and property insurance before they depart from their country.
Currency and Credit Cards
The currency unit in Poland is the Polish Złoty (zł or PLN) which is subdivided into 100 grosze (gr). The current average exchange rates to most of the currencies can be checked at https://nbp.pl/en/statistic-and-financial-reporting/rates/table-a/. In June 2025 it was about 4.25 PLN for 1 EUR and 3.75 PLN for 1 USD. Delegates may change foreign currency and travelers checks at several banks located in the city center as well as in many exchange bureaus, at the railway station, at the airport or in many others places. International credit cards are widely accepted in hotels, restaurants, cash machines and shops.
Electricity
Electricity supply is 230 V / 50 Hz. In Poland, the standard E-type and F-type (Schuko) sockets and plugs dominate. Type E is a socket with a grounding pin, while type F has two sources for grounding, which are available opposite each other.
Climate and Clothing
The weather in June in Warsaw is usually warm and pleasant, however the evenings and nights might be sometimes quite cold. The average daytime temperature varies from 11 degrees to 24 degrees Celsius. There is a possibility of rain, so an umbrella, light raincoat and comfortable shoes are advisable.
Shopping
Most shops (except for food stores) are open from 11:00 until 19:00 except Sundays when they are closed. Some department stores may open earlier or close later on weekdays as well as on Saturdays.
Polish craftwork is fascinating. Polish souvenirs include glass, hand-woven baskets, paper cut-outs and crystal. One of the most popular souvenirs is amber from the Baltic Sea. Each individual piece can be fashioned into a pendant, ring, bracelet, or earrings. Most highly prized is amber with a prehistoric insect preserved inside, though it is a rare find. Poland is also known for its silver jeweler, which is sometimes combined with amber to create uniquely Polish pieces.
Food
Poles are known for their hospitality and love of food. Polish meals offer a wide selection ranging from fresh game in season to Baltic herring. Red beet soup or borsch, is well-known, as are Polish sausages (kiełbasa) and stuffed cabbage (gołąbki). Dumplings (pierogi) come stuffed with meat, potatoes, blueberries, or sauerkraut and mushrooms. Bigos is a stew of meat and sauerkraut, while roast duck comes stuffed with apples. For dessert, try pastries with poppy seeds, or perhaps a Polish donut filled with preserved fruit (pączek).
