First, I want to tell you that there is NO WAY to obtain a second passport EXCEPT for the countries in the Carribeans that everyone knows about. There are some other places with special long stay visas as well. All you need to do is run a search online and find these places. Nomad Capitalist can NOT help you beyond what you can do for yourself for free. But he will charge you several thousands of dollars and up to $50,000 for the promise of getting you a passport in some other country. He has NO way to get you any visas or passports beyond your own abilities. He is a scam artist and liar. Once you are foolish enough to send him money, you will not be able to get a refund after his efforts (and I don't even think he spends any efforts once he gets your money because he knows it's a waste of time to do something that's impossible). He spends ALL of his time making youtube videos and marketing his scam company with BS and lies.
There is now even a website that someone made to expose him nomadcapitalistscam.com/
