I found Where Can I live when I was searching for information on the Friendly Nations visa in Panama. Their articles are really informative and well written. They offered for us to use their lawyer and I was skeptical at first but read about their assessment process so thought I would give it a go. Their lawyer was really helpful, organized, and explained exactly what I needed to do. I would highly recommend going with their lawyers rather than trying to find a good one yourself.
This is an amazing tool. It checks your personal information against official immigration info and then tells you exactly where you can move to. Www, wherecai.live showed my options I have never thought about. The website also has a good resources on international living.
The site lets you find out where you might be able to live / get residency based on factors such as family, investment and so on. I found out I could get an Irish passport even though I didn't think I could... so I'm Brexit-proofed!
