I have a investment interest expense deduction that I may use at sometime to benefit me on my taxes. I have long term property that has been sold in Norway. I am aware that I will have to pay 28% tax to Norway and also include it as income on my taxes. I think I should be able to take a foreign tax credit . Am I able to use my investment interest expense deduction carried forward to eliminate my 28% to Norway?

I do not think so. However, you REALLY need to get face-to-face tax advice from an experienced tax professional who can consider all aspects of your tax situation.
