I'm currently in the process of moving to France (less than 2 weeks away!) so I've got some recent experience. The first question is what visa you need. If your husband is a dual citizen (European I assume) then as his spouse you should be able to easily get one. I know in France you don't need to get a visa in advance. Once you arrive you go to the nearest prefecture and register yourself. Denmark is probably similar but you should verify. I'm also assuming you're retired or nearly so, therefore I won't discuss working etc which is a whole other ballpark. The real question you should ask yourself is if you want to permanently relocate or if this will be temporary. In our case the move will be permanent but we plan to rent out our house for at least a couple years in case things don't work out and we want to return. If your house is your permanent residence and you've lived there for the last 2 years you can rent for up to 3 years and still not pay capital gains taxes when you sell. I also would persuade you to not ship over furniture unless it's near and dear to your heart. Unless you live in the countryside most houses/apartments aren't the same size as what you would find in the Bay Area. In our case we are moving from a 3/2 house in Oakland with a basement and garage to a 2/1 apartment in Paris. Needless to say there was no way our stuff was going to fit. We ended selling/getting rid of everything and only shipped a few boxes over. We will buy all new furniture over there and have a fresh start. I recommend doing a search on Facebook for 'American expats in Denmark'. You'll get a lot of help there. I also recommend you keep a US bank account. There are plenty of transfer services that can convert your US dollars to Euros (Revolut, Transferwise etc).
