No, it just needs some time and effort, and you need a good lawyer (I remember lcamtuf writing about it on his blog). You just need a residence (even if it's a coach (or basement) at your friend's) in a country for a few years; you need to visit periodically and ensure your lawyer is advancing your case. 3-5 years later (depending on the country, of course), you get citizenship and a passport. It's absolutely doable without too much of an effect on your financials if you work in tech or a similarly well-paid job. If you do this consistently over the years, you'd have 3-4 passports by your forties. Unfortunately, people under forty rarely seem to think that far ahead. I'm personally starting to really worry about retirement, but I'm too old and too ill now to jump ship like that...
BTW, I'd like to send you a private message - is the `pro` (at) your.domain a good way to do that?
I’m a citizen of three countries. I don’t know that it is all that unusual to have multiple citizenships, particularly for the very rich (a group I am most deinfitely not a part of) who might access citizenship via investment in a country.
To be clear anyone with a few million in savings can take on multiple citizenships as a hobby, maybe OP just considers it table stakes for billionaires, as in, why wouldn't you.
St kitts and Nevis is only a quarter mil, tho I don't know what benefit that would confer unless you're coming from a country without visa free travel
And for what it's worth, UAE citizenship is not for sale directly, you have to actually live there long term
Residency is pretty much for sale in the UAE. However it is virtually impossible to be naturalized in the UAE through the official route. Most of the country is foreign born and there are lots of benefits to being a citizen so this deliberate. It requires something like 30 years of uninterrupted residency. Most people who get it are basically granted citizenship by a king. That’s why when you look at the list of Emiratis on Wikipedia the ones who aren’t Arab are almost entirely elite athletes and businessmen with political connections. It’s interesting that France and the UAE granted him citizenship and hacked his phone together.
