Is a visa necessary?
Unless you’re moving back to your country of origin (where you have a valid passport), you will need a visa. A visa is an official government authorization of your destination country which allows you to remain within its borders for a specified purpose and time period. This may be issued as a separate document, or stamped onto your passport. There are many different types of visas, and the kind that you need is dependant upon the country you are moving to, the length of time you intend to remain there, and the purpose of your stay. Some of these include: short-stay visa (tourist visa, transit visa, business visa, medical visa), long-stay visa (for longer, but still finite stays), and residence visa (for those seeking long-term residence).
