Getting a resident visa to a new country where you plan to live on isn't that easy. If you have no money, you'll have to go through with years of working and living there. While there are golden ticket visas that are a shortcut process to your resident visa and passport and that's through investing or buying it to those countries. Many countries offer this and I think many are choosing those countries in the Carribbean part because it's easy to get a passport there and you can live there if you have money. Most likely it's ranging from $100k and more than $250k.
There are many countries that grant asylum visas to citizens of countries considered unsafe, such as Syria before the fall of the Assad regime and Afghanistan today. If World War III breaks out, the countries involved in the conflict will certainly no longer be considered safe, and citizens will be entitled to seek asylum in safe countries. These safe countries may not be able to provide significant support. For example, if I were granted asylum in Switzerland, the government would provide me with a salary until I could find a job, but compared to other countries, I might not be able to receive anything.
That's another case but for people that are preparing before it happens, the normal path is what they will seek for. It's good to know that there are asylum visas and you made me remember that person who guided Drew Binsky on Afghanistan with one of his vlogs and travel there. And when the Taliban group took over the government there, he's granted asylum and went to Australia. So, thanks for explaining that. It's the path of those people that want to relocate themselves into a safer country as long as they're welcome there.
Unfortunately, this isn't available to everyone. In most cases, if not all, you must prove that you were persecuted in your country in order to be granted a refugee visa. Take Afghanistan, for example. Afghanistan is currently considered a stable country, free of conflict and war after the Taliban regained power following the US withdrawal. This means that life in Afghanistan is relatively safe, and therefore no one can complain about the lack of security. At the same time, there is a freedom crisis in Afghanistan. Therefore, women, for example, may apply for a refugee visa because they are not allowed to study and enjoy personal freedoms, or journalists who want to practice their profession with greater freedom. This means that some form of harm must be proven before they can be granted asylum in another country.
