Editor's Note: Those who choose to travel are strongly encouraged to check local government restrictions, rules, and safety measures related to COVID-19 and take personal comfort levels and health conditions into consideration before departure.
1. Portugal
The fashionable country due west of Spain is attracting young expats in recent years, particularly entrepreneurs, given its incredible value and welcoming business incentives that help stretch your hard-earned dollars. Take the second city of Porto, buzzing with modern and creative energy as a manufacturing and textile hub, with a slew of new designers who have made the city their home. Following decades of decline in the late 20th century, Porto's cobbled streets today are filled with cool cafes, restaurants, and boutiques selling goods from local weavers and ceramists. On a day off, take advantage of the city's art district, historic churches, and palaces, as well as the Douro River that leads to the oldest wine region in Europe (Alto Douro). Less than an hour from Porto is Portugal's third city, called Braga, which, for its part, offers a reduced tax rate for start-ups. Nicknamed the "Rome of Portugal" thanks to its Baroque architecture, Braga also offers attractive green spaces, international schools, and high-tech companies for qualified candidates. Further south is the Algarve coast with more than 300 sunny days per year for digital nomads, families, and retirees who enjoy life at the beach. You can also check out the nine islands in the Azores — some offer incentives to attract businesses and start-ups. No matter where you choose, you'll be hard-pressed to find a kinder nation to call home.
2. Costa Rica
Relocating to well-trodden Costa Rica isn't a novel idea for anyone who has ever visited the country (and likely met a few friendly expats along the way), but there's a reason for its persisting popularity. Situated between the Pacific and Caribbean coasts, this utopic Central American nation wins people over with volcanoes, cloud forests, and exotic wildlife in the form of sloths, capuchin monkeys, and toucans. More than that, it's the Pura Vida ("Pure Life") philosophy for good living, which sums up this peaceful Spanish-speaking gem. Sweetening the deal, the country offers expats a straightforward residence program, affordable dental and healthcare, a stable democracy, and easy flights to the U.S. from two international airports. While the capital of San Jose has a notable food and arts scene, expats can head for either coast for long stretches of undeveloped beaches, seaside villages, surfing and yoga classes, neighborly expat communities, and business ventures often tied to eco-tourism. If you prioritize a healthy, laid-back lifestyle surrounded by natural beauty with an evergreen cool factor that is hard to imitate anywhere else, then this might be the place for you.
3. South Korea
The country that invented K-Pop, K-barbeque, K-beauty, and 24-hour jjimjilbangs (Korean bathhouses), draws expats wanting to be a part of this living and breathing epicenter for popular culture. The sleek city of Seoul, Asia's third-largest economy, will surround you with killer restaurants, shopping, entertainment, night markets, and a high-tech scene with international workers who partake in the work-hard, play-hard mentality. Professionals based here will find tight-knit social groups and regular networking events for those looking to hob-nob over soju cocktails. But don't overlook Busan, South Korea's edgy second city with beaches, fresh fish, and an international film festival. (Fun fact: You can take a ferry to Japan from here.) No matter where you decide to live on the peninsula, enjoy access to rugged mountains and thousands of islands offering plenty of outdoor adventures like winter skiing and treks to 7th-century temples. South Korea is a safe place to live despite its close proximity to North Korea, but stay cognizant of the situation.
4. Canada
As President Biden recently put it to Prime Minister Trudeau, there is no closer friend to the United States than Canada. Regardless of who is — or isn't — in office, Canada remains a top contender for American expats for a number of reasons that may include affordable education, cultural diversity, stability, and countless adventures in the unspoiled natural wilderness. If seeking a job, consider the largest city of Toronto, often compared to the Big Apple, where the majority of Canada's work opportunities are located. There are plenty of other livable cities to choose from like Vancouver, surrounded by sea and mountains, which may include weekend trips to Tofino, a year-round surf town on the edge of the continent. Or Calgary, which is experiencing a renaissance with cool eateries, hip neighborhoods, and proximity to the best trails in the Canadian Rockies (
Banff National Park is an hour away). Then there are the French-infused cities of Montreal and Quebec City in the east for those who want a slice of European living without the long flights. Depending on your circumstances, you can take your pick between several different ways to make the move; start by checking for eligibility if one of your
parents or grandparents was born there.
5. Austria
This Central European country can have you hiking in the Alps in the morning and enjoying a performance in a famous opera house later that evening. Austria's capital, Vienna, has been recognized in Europe for its
high quality of life and low crime rates, as well as an exciting food and wine scene, focused on organic, local ingredients. It's also a good choice for those looking for affordability, healthcare, and international schools. Further south is the youthful city of Graz, which offers its own version of Renaissance and Baroque architecture as well abundant parks and upbeat nightlife. Beyond all of the aforementioned pleasures of living in Austria, if the idea of being surrounded by Italy, Switzerland, Liechtenstein, Germany, Czech Republic, Slovakia, Hungary, and Slovenia gets your heart pumping, then you may have found your place.
