The visa requirements for your nationality will vary depending on the country or territory you plan to visit, as most territories have their own individual visa policies with different requirements for different foreign citizens.
It may not be necessary to obtain a travel document to visit your country of destination, as many countries have a passport nationality list of visa-exempt citizens who they permit to enter visa-free for short periods of time.
However, it may be necessary to obtain either a visa or electronic travel visa authorization for your nationality to visit your desired destination.
If you do require a electronic visa for a specific country, an online visa application may be available for your nationality. Otherwise, it may be necessary to apply for an embassy visa in person from the nearest diplomatic office of the destination country.
