Visitor's visa and residence permit
How to apply for a tourist visa to Norway
Citizens of Irelando do not need a visitor's visa or a residence permit, but if you plan to stay longer than 90 days, you must register with the police.
The rules for Irish citizens also apply for all other EU/EEA citizens. If you are a non-EU/EEA citizen living in Ireland, and not sure whether or not you need a visa, you may check that on this link, Want to apply - UDI.
Should it be so that you need a visa to visit Norway, you will need to get in touch with the Danish Embassy, Travel And Residence (um.dk), to get information on documents and requirements, and also to make an appointment to hand in your application.
All contact regarding visas, must be directed to the Danish Embassy, as we don't have any information about requirements, processing time, etc.
