Category of visa to apply

Dear friends,
     I will be much happy to know more about the visa category to select and apply for fiance,
I am a little confused to which form I should fill.
Is it the same as “Au Pair" visa?
I will be much happy to know from you.
Thank you all.

The category for applying Fiancee Visa in UDI is under the Family Reunification

https://www.udi.no/en/want-to-apply/family-immigration/


Just select the fiancee option.

As mentioned by Alina above, the fiancee category in under Family Immigration

Under What kind of family member are you?, choose the third one which says Those getting married

Hope that helps!

If you want to apply for finance visa then you need to fill form for finance visa and fulfill its requirements, not for au pair. Some steps while applying can be similar category is totally different,.
