More Americans are moving overseas to escape high costs, find better healthcare, or enjoy a slower lifestyle. “There’s a growing desire for simplicity, slower living, and meaningful experiences,” especially among retirees and remote workers. Countries like Portugal, Thailand, and Mexico became popular for their flexible visa options.

But now, the welcome mat is being rolled back. In 2025, several countries are tightening immigration rules, even for U.S. citizens. From “new visa rules and travel authorizations to stricter enforcement,” the once-easy move abroad is now more complex.

The shift comes from local concerns—rising rents, overcrowding, job competition—and bigger issues like national security or political tensions. As cities get overwhelmed, governments are pushing back. “It’s not personal,” but the global travel boom is forcing countries to set limits.

With more Americans living the digital nomad life or retiring abroad, immigration systems are under pressure. That means “what used to be a relatively straightforward move is now more complicated and uncertain.”

If you’re planning to relocate overseas, understanding the new barriers is essential—because five key countries are now making it harder for Americans to settle in.
