If you suddenly find yourself motivated to permanently escape the USA, there are a few ways to do it. Most people think the only option is to marry someone with citizenship of your desired country, but a lot of nations actually offer economic citizenship. Make an investment in the country of your choice and that becomes your point of entry. Here is where I'd go if an American exit was in the near future. Please note, this information can change quickly, especially since we are in an unstable political environment, so use this as a starting point to kick off additional research!
The economic citizenship program of Dominica is one of the most inexpensive options you'l find. It can be yours for just a $100,000 investment, plus there are no residency requirements. Go ahead an buy a property, then AirBnb the hell out of it until your turn a profit! And since Dominica is a member of the British commonwealth, you'll get the added perk of visa-free travel through the UK, Hong Kong, Singapore and many others. Dominica has also recently applied for visa-free travel to all EU member nations, which if approved is a huge added value that may drive-up the cost, so if you are thinking about, it start making moves fast.
Another affordable option is Saint Lucia. The $100,000 cost and 2-3 month processing speed make this a desirable option, and the fee includes dependent children under 25 and dependent parents over the age of 65, with no residency requirements. Plus you'll get visa free travel to over 100 other nations and no taxes on your worldwide income.
Turks & Caicos
Invest $300,000 to build a home in paradise or remodel a distressed property, and you'll get a quick residency permit. You or your family members have to be the primary residents, so you won't get away with renting it out full time. If for some reason the idea of establishing residency on a tropical island isn't your speed, just invest $750,000 in a local business and you'll still get the same residency perks.
The Comoros Islands
If you really want to go off the beaten path, fly over to The Comoros Islands. The archipelago off the Eastern Coast of Africa. You'll get visa free travel to over 40 countries worldwide, though that doesn't include Europe, the UK or Canada. However for only a $45,000 investment, that is a non-concern.
