Unless you are from a visa-exempt country, you will need a visitor visa to enter these countries whether you are coming as a student, temporary worker, or simply to visit.
The main purpose of a visitor visa is to meet someone in that country. To apply for a visitor visa, you need to get an invitation letter from whom you want to meet.
There are two types of visitor visas: Single entry visas and multiple-entry visas. A single-entry visa allows foreign nationals to enter the country for one-time only. A multiple-entry visa allows holders to enter and leave the country as often as they want as long as the visa is valid. You don’t need to choose which kind to apply for, applicants are automatically considered for multiple-entry visas and are only issued single-entry visas under unique circumstances.
