Visa requirements range by country and are determined by the traveller’s nationality, as well as the length and purpose of the intended stay. Depending on the purpose of your visit, you may be permitted to enter your destination country without a visa, or you may need to obtain a visa or an electronic travel authorization.
When a travel document is expected to enter the country of destination, all travellers should check the visa requirements for their nationality.
For transit, business, or tourist travel, many countries require certain nationalities to obtain a visa in advance of travel via an embassy or consulate, while others allow select individuals to acquire a visa online through an electronic application system.
