The country where expats are most content with their professional lives.

According to InterNations' latest Expat Insider survey, expats in Denmark are among the happiest with their work lives.

Among other aspects, job satisfaction, career opportunities, and work-life balance are the factors that make the Nordic country the best place to work.

The survey results from over 12,500 foreign residents cover four broad work-related categories, including career prospects, salary and job security, work culture and satisfaction, and work and leisure.

Denmark excels in both work culture and satisfaction, as well as work and leisure.

In Denmark, 84% of expats are content with their work-life balance, which is higher than the global average of 60%. Additionally, a similar percentage of expats are happy with their work hours and, on average, work 39.2 hours per week, which is lower than the global average of 42.5 hours.

The top 10 countries where expats are most content with their professional experiences overseas are:

1. Denmark
2. Saudi Arabia
3. Belgium
4. Netherlands
5. Luxembourg
6. United Arab Emirates
7. Australia
8. Mexico
9. Indonesia
10. Austria

Ilana Buhl, a CNBC Make It contributor and American teacher who relocated to Denmark, experienced numerous positive changes in her work life after moving from Texas to Copenhagen, including shorter workweeks, more defined boundaries around off-hours, five weeks of paid vacation, and a higher salary to offset the lower cost of living.

She enjoys robust public transit, public health care, affordable day care, and ample maternity leave outside of work.

Denmark regularly ranks among the happiest countries globally due to several contributing factors, as stated in the annual World Happiness Report.

Saudi Arabia ranks No. 2 with 75% of respondents stating that moving there has enhanced their career prospects, compared to the global average of 56%. Additionally, 63% of newcomers relocate to Saudi Arabia for work and express satisfaction with the local economy.

A third of expats worldwide cite job opportunities as the reason for their relocation.

The longest workweek for expats in Saudi Arabia may be a significant disadvantage, with reports indicating that they typically work 47.8 hours per week.

Belgium ranks highly among expats for job security, local job market, and career opportunities.

Belgian expats appreciate the flexibility they experience in the workplace, particularly the 68% who can work remotely, and their shorter-than-average full-time workweek of 40.8 hours.

According to the InterNations survey, Panama was ranked as the top country for expats overall, taking into account various life and financial factors, including quality of life, ease of settling in, working abroad, personal finance, and an "expat essentials" index that covers housing, administration, language, and digital life.
