Depends on the country.

It may also matter how much money you make, whether you're married to someone who is taking benefits, and so on. Even for the countries I've lived in, it's been a mess to find out.

And when you do find out, sometimes you find there's some loophole. For instance, if you try to bring a non-EU spouse to Denmark, it's hard if you have low income. However, Sweden is right across the water from Denmark, and there's a bridge connecting them. And the Swedes have a different national law. Also there's EU law, which is another way to get in.

Oh, and the UK voted to leave the EU, so there will be even more legal spaghetti.

Try to narrow down what countries you're interested in, and find someone who can help you.
