A visa is permission issued by a country for a foreign national to travel for a stated purpose and request entry under defined conditions. It may appear as a sticker, stamp or electronic record. A visa is important, but it is only one part of the border process.
Visa and passport: different roles
A passport identifies the traveller and is issued by the traveller’s own country. A visa is issued or authorised by the destination. Most visa applications are tied to one passport, so replacing that passport may affect the visa.
Common visa purposes
- Tourism and private visits
- Business meetings and short professional activities
- Study or training
- Employment
- Investment
- Family reunion or dependent residence
- Transit
Validity is not the same as permitted stay
The validity period shows when the visa may be used. The permitted stay shows how long the traveller may remain after entry. A visa valid for several months may still allow only a short stay on each visit.
Single and multiple entry
A single-entry visa is normally used once; leaving may end its usefulness. A multiple-entry visa can be used more than once during its validity, but each entry must still comply with the purpose and stay limit.
The border decision
A visa allows the holder to travel to the border and request admission. Immigration officers can examine the purpose, documents and circumstances before making the final decision. Carry evidence that supports the trip.
Use a visa responsibly
- Do not work on a visitor visa
- Leave or extend lawfully before the permitted stay expires
- Report changes required by local law
- Keep electronic approvals accessible offline
- Read every condition attached to the visa
