An employee who is sent by their employer to live and work in a country other than their home country, typically on a defined assignment lasting one to five years.
Key Takeaways
An expatriate, commonly shortened to expat, is an employee who relocates to another country at their employer's request or with their employer's sponsorship. The term comes from Latin: "ex" (out of) and "patria" (homeland). In HR, it specifically refers to company-sponsored relocations, not self-initiated moves. The distinction matters because expatriates receive structured support packages that can include housing, education allowances, tax equalization, relocation logistics, and cultural training. Someone who moves to another country on their own and finds a local job isn't an expatriate in the HR sense. They're a local hire. Expatriates have been a fixture of international business since multinational corporations expanded in the mid-20th century. The model was built around sending senior executives from headquarters to manage overseas operations. That's still common, but today's expatriate population is more diverse. It includes mid-career specialists, technical experts, young high-potentials on developmental assignments, and increasingly, employees who request international experience as part of their career path. The economics of expatriation have also shifted. With assignment costs running $300,000 to $500,000 per year, companies are much more deliberate about when an expat assignment is the right solution versus hiring locally or using short-term alternatives.
Companies use different assignment structures depending on business needs, cost constraints, and the employee's career stage.
| Assignment Type | Duration | Package Level | Common Purpose |
|---|---|---|---|
| Long-term assignment (LTA) | 1 to 5 years | Full expat package: housing, schooling, tax equalization, relocation | Senior leadership roles, market entry, complex knowledge transfer |
| Short-term assignment (STA) | 3 to 12 months | Reduced package: serviced apartment, per diem, no family relocation | Project delivery, temporary skill gaps, training initiatives |
| Extended business travel | Under 3 months | Travel and living allowance only | Audits, client engagements, short-term project support |
| Developmental assignment | 6 to 24 months | Reduced or local-plus package | High-potential talent development, cross-cultural exposure |
| Strategic/executive assignment | 2 to 4 years | Premium package with enhanced benefits | C-suite or regional leadership, major market expansion |
| Localization (local-plus) | Indefinite | Local salary with select expat benefits | Permanent transfer where employee transitions to local terms over time |
Expat compensation packages are designed to keep the employee financially whole while abroad and incentivize accepting the assignment.
The most common compensation method for expatriates. It calculates what the employee would spend on housing, taxes, goods, and services at home, then adjusts the package so they can maintain the same standard of living in the host country. The company covers any cost differential. If housing costs 40% more in London than in Dallas, the company pays the difference. This approach is transparent and equitable but administratively heavy. It requires annual recalculations as exchange rates, tax laws, and cost-of-living indices change.
A full expatriate package typically includes base salary (usually maintained in home-country currency), a mobility or assignment premium (10% to 25% of base), housing allowance or company-provided accommodation, education allowance for dependent children, cost-of-living adjustment (COLA) for higher-cost locations, hardship allowance for difficult postings, annual home leave flights for the employee and family, relocation allowance covering moving costs, tax equalization ensuring no additional tax burden, and health insurance valid in the host country.
Increasingly, companies use local-plus packages instead of full balance sheet. The employee receives a local salary benchmarked to the host country market plus select additional benefits: maybe housing, education, or home leave, but not the full suite. Local-plus costs 30% to 50% less than traditional packages and is common for younger assignees, developmental moves, and situations where the employee requested the assignment. The trade-off is that some employees won't accept assignments without the financial cushion of a full package.
Managing expatriates is one of the most complex and expensive activities in HR.
Picking the right person for an international assignment involves more than checking their resume.
Data on the scale, cost, and outcomes of expatriate programs worldwide.
The decision between sending an expat and hiring locally depends on business needs, cost tolerance, and talent availability.
| Factor | Expatriate | Local Hire |
|---|---|---|
| Cost | 2x to 3x local salary with full package | Local market rate |
| Time to productivity | 3 to 6 months (cultural adjustment) | Weeks (already knows the market) |
| Knowledge transfer | Brings HQ knowledge and processes | Brings local market knowledge |
| Control | High alignment with HQ culture and strategy | May need time to absorb company culture |
| Compliance complexity | Dual-country tax, immigration, benefits | Single-country employment |
| Duration suitability | Best for 1 to 5 year defined periods | Best for permanent roles |
