When you cross the border into the Schengen area, you will have to present:
- your passport with the visa sticker
- proof that you have enough money to support yourself during your stay (e.g. cash or a credit card). If you have a guarantee form, you should also bring a copy of this with you.
- documentation showing the purpose of your visit, such as an invitation, hotel reservation, etc.
- a return or round trip ticket if you are visiting the Schengen area for tourist purposes or private reasons
You may be asked to provide fingerprints by the border control officer, in which case these will be compared with the fingerprints provided when you applied for your visa.
As long as your visa is valid, you can travel around freely in the Schengen area, or in the specific Schengen countries covered by the visa. If you leave the Schengen area, for example to visit the UK or Svalbard, you will need a multiple entry visa.
Be aware that even though you have been granted a visa, the border control officer will be able to refuse you entry into Norway if you at the time of travelling no longer fulfil the conditions for having a visa. This may, for example, be the case if you cannot show the border control officer documentation that you have sufficient funds for the whole of your stay in Norway.
