Important links
UDI – This is your first and last stop for immigration.
UDI Waiting Times – Constantly changing and are usually quite long.
Immigration Act - In case you want to really learn the laws. This is in Norwegian, but a translation tool will work well enough.
Norwegian Customs: Moving to Norway – Some items may be taxed if they are brought into Norway. Generally personal items are not taxed, however some may be. This applies to new items, food products, alcohol/tobacco, weapons, work-related equpiment, etc...Cars are also taxed on import.
Study in Norway for information about studying in Norway
Nokut - which allows you to check to see if your education satisfies the entry requirements
Bringing your pets to Norway – This link helps you learn which animals are allowed and which are not, including which dog breeds are banned, and the steps you'll need to follow to import your pet including the vaccines and documents you’ll need to make sure your pet is accepted at the border.
If you are going to bring your pet, I cannot stress enough how important it is that you know the rules inside and out and that you make sure your pet is 100% compliant with the rules. If you arrive at the border without meeting the requirements your pet may be quarantined, returned to its point of departure, or euthanized (and you will incur those costs).
If you are flying with your pet, double check that your airline will accept pets in the cargo hold or if they'll need to be shipped separately. Pets may only travel during certain times of the year (there are temperature restrictions that vary based on airline). Additionally, Third-Country Nationals (non EU/EEA) pets can only arrive at two airports in Norway (Oslo, Kirkenes -- Tromsø allows pets travelling from Svalbard).
Altinn – an over view on how to start and operate a business in Norway. NB: Altinn is your dialogue with the business, private citizens, and government services such as tax returns/statements and other digital forms.
NAV – a good place to look for jobs; also the place to find services and benefits.
FINN – the classifieds section for the modern Norwegian. This is where you can look for jobs and buy or sell items/services.
New In Norway - A useful site to guide you through the process of moving to Norway and the first steps of getting settled in Norway.
IMDi – where you can find all the information on language classes and the introduction act. (Note: the Norwegian page is more comprehensive).
Directive on Free Movement – applicable for EEA/EU citizens/family members of EU/EEA citizens only. Very good for Norwegians to also know your rights to free movement in the EEA/EU!!
Statens Vegvesen – Norwegian Road Authority where you deal with all things related to your vehicle including licencing, EU control, registration, etc... Some countries have an agreement with Norway that will allow you to exchange your foreign licence (with or without a road test). For those countries that do not have such agreements, you will need to go through the same process as Norwegians to get your licence, which includes mandatory driver training through an accredited traffic school. If you can exchange your licence, you usually only have one year from the time you were granted your residence permit, so it is wise to do that as soon as possible.
Norwegian Tax Office – You will need to get in touch with these folks if you’re going to work in Norway.
Helse Norge - A place to see your health information including your patient journal, your electronic prescriptions, change your doctor, etc...
You can read about banking here and here. The pages are a little old, but it will get you started. Most common banks include Sparebank1, DNB, Handelsbanken Norway, Sbanken as well as many other smaller savings banks.
Once you get a bank account, you'll need to get BankID which is critical to accessing many Norwegian services including Statens Vegvesen, Helse Norge, Altinn, etc... BankID serves as a digital signature.
The most popular telecom companies include Telenor, Telia, OneCall, TalkMore. You will need a person number (granted to you once you have a residence permit) in order to get any subscription based phone plan. EU phones will work in Norway and with the EU’s “roam like home” directive. Non-EU folks may need to get a pre-paid phone card (kontantkort) until you can get a subscription.
No matter where you are coming from, I recommend that anyone considering a move to another country look into culture shock. Lots of immigration attempts fail in part because a failure to recognize and address culture shock.
There was a good discussion about the difficulties of moving to Norway (or any other new country) that you can read here. You can learn about culture shock here, and here, and here, and also here.
While it may not be required for most applications, from experience, it is a good idea to get a certified copy of some important documents from back home. Getting certified (and potentially notarized) copies of diplomas/transcripts, your birth certificate, divorce proceedings, etc... will potentially save you a lot of time, money, and annoyance as trying to get these things while you are abroad is much, much harder.
