Dual citizenship

Me and my future husband planned to live in Norway for 10 years. After that we planned to retire in Malaysia. So we plan to apply for dual citizenship. How to go about it?

Norway does not allow dual citizenship unless you can prove there is going to be undue hardship (financial or otherwise) in giving up your other citizenship.

Thank you for the informations. So In my case, i have no choice but to apply for sponsal visa. How do i go about sponsal visa for How many years is alllowed In Norway?

I recommend you read through the immigration authority's website, and check out other threads in this forum
