Adding onto the statement about working in a foreign country for citizenship, you can actually gain a self-employment visa to many countries on the condition that you have enough money to sustain yourself without government assistance, or make enough money to do so from your own business. It’s not allowed to work for someone else under this type of visa, and you can’t change it into a normal work visa, so you have to make all the money by yourself or already have it saved up. Plus you generally have to have like €10K-15K deposited in a government bank account that you’re not allowed to withdraw from, as a guarantee that you won’t be a liability to the government in case you can no longer sustain yourself – in that case your visa won’t get renewed. After a few years of this you can apply for permanent residence. But realistically you could just apply for DAFT in the Netherlands, a self-employment visa in Portugal or Germany, etc. and as long as you have like 5 years of living costs saved up, on top of the required deposit, you might be able to just live your life until you eventually qualify for permanent residence. But that’s only really an option if you have a ton of money, most people need to actually be able to sustain their own business.
