A trip to Singapore, regardless of its purpose, will most likely require you to obtain a visa before departure. The only exception includes the citizens of the 34 countries that are visa-exempt. They can stay in Singapore for periods that vary from 30 to 90 days, depending on the country of origin. However, all the other nationalities need a visa to cross Singapore’s borders and stay. Even so, keep in mind that there are many Singapore Visa Types.
