Visa options for Qatar
Electronic Hayya visa
Travelers need a visa to visit Qatar for Business or Tourism. A Hayya eVisa is the fastest and easiest way to obtain a Qatar visa because travelers can submit their applications and supporting documents online. Once the application is approved, travelers receive their eVisa confirmation electronically. A valid visa is required to board the flight. If the visa is expired or doesn’t match the traveler’s passport information, travelers will not be able to board their flight.
