A travel visa is a type with a very limited duration attached to it and it is only intended for pleasure trips. A travel visa is to have no work associated with it and can be given a duration as short as three days, though the duration must be discussed up front at the application. Each country has different specifications associated with it for purposes of a travel visa and these criteria must be met before a travel visa can be granted. No business can be attached to or associated with a travel visa so the application process will be very specific in terms of intent and duration. A valid passport is usually used in conjunction with a travel visa, so it's an important part of the process.
