15 Oct The Traditional Expat Assignment Is Not Disappearing. It Is Being Redesigned

For years, the traditional expatriate assignment followed a familiar model. An employee and often a family relocated overseas for several years, with the employer providing housing, tax support, schooling, cost-of-living allowances and other benefits designed to make the move workable.

That model has not disappeared. But companies are becoming much more selective about when they use it, what they pay for and whether a long-term assignment is really the best way to meet a business need.

AIRINC’s 2026 Long-Term Assignment Policy Trends describes long-term assignments as one of the most established parts of global mobility. They continue to support leadership development, knowledge transfer, operational continuity and capability building. What is changing is how those assignments are designed and managed. 

Why companies still need long-term assignments

Some work simply requires someone to be there.

A manufacturer opening a new plant may need an experienced engineering leader on the ground for two years to establish procedures, train local employees and work with suppliers. A company entering a new market may need an executive who can build relationships and develop a local organization. Other assignments may be intended specifically to develop future leaders by giving them experience managing in another market.

Those objectives are difficult to achieve through occasional business trips or video calls.

AIRINC defines a long-term assignment as generally lasting at least 12 months, with maximum durations commonly set at three or five years. It reports that home-based, tax-equalized arrangements remain standard at many companies even as employers experiment with other forms of mobility. 

Mercer reaches a similar conclusion. Its 2025 Talent Mobility Outlook found that only 18% of respondents expected long-term assignments to increase, but 53% expected their numbers to remain stable. In other words, the traditional expatriate assignment may no longer be growing rapidly, but predictions of its disappearance have not materialized.

What is changing is the package

Companies are increasingly trying to preserve the benefits of international assignments without automatically providing the same expensive package to every employee.

AIRINC found that only 23% of organizations were granting flexibility through policy exceptions in 2026, compared with 33% in 2022. At the same time, 49% were using lump sums, up from 37%. Fifty-five percent now provide miscellaneous relocation allowances as flat amounts, while 41% use a cash allowance or default cash approach for shipping. 

The trend suggests that flexibility is not disappearing. It is becoming more structured.

Instead of negotiating benefits case by case, companies can establish different levels of support depending on the employee, destination and reason for the assignment. A senior executive opening an important market may require one level of support, while an employee taking an overseas role primarily for career development may receive another.

Housing remains an important part of the equation as well. AIRINC found companies refining housing standards while maintaining substantial support for assignees, illustrating how employers are looking for greater cost predictability without removing benefits that make an assignment practical. 

One assignment model no longer fits every situation

The larger change is that long-term assignments now sit within a much broader mobility portfolio.

Short-term assignments, international commuters, permanent transfers, local-plus arrangements, rotations, business travel and remote work all give companies alternatives to moving an employee and family abroad for several years.

KPMG’s 2025 Global Mobility Benchmarking Report found that 70% of respondents use short-term assignments, often as a lower-cost alternative to traditional long-term moves. The report describes this as part of a shift toward more agile and project-oriented deployment. 

Mercer also found short-term assignments were the international mobility category most likely to grow, with 34% expecting increases. Permanent moves, international hires and remote-working arrangements are also becoming established parts of the mobility mix. 

That does not make the long-term assignment obsolete. It simply means companies have more choices.

A six-month technology implementation may call for a short-term assignment. A regional executive may be able to commute between nearby markets. Someone making a permanent career move may be better suited to a permanent transfer rather than a traditional expatriate package.

The long-term assignment becomes most valuable when sustained physical presence produces something those alternatives cannot.

Employees are also changing the equation

The design of assignments is becoming more employee-centered for another reason: convincing people to move can be difficult.

EY’s 2026 Mobility Reimagined Survey found that 88% of mobile employees consider flexibility in mobility policy important, up from 70% a year earlier. Gen Z employees were nearly twice as likely as other generations to describe flexibility as extremely important. Younger employees also placed particular value on skill development and opportunities for their families. That does not necessarily mean younger workers are unwilling to relocate. It suggests they may evaluate an assignment differently. Career development, partner employment, family needs and what happens after the assignment can matter as much as the compensation package.

The payoff for employers can be significant. EY found that 80% of employees said a recent international mobility experience made them more likely to stay with their employer. 

The assignment now needs a clearer reason

The result is a more deliberate approach to expatriate assignments.

Before sending someone abroad for several years, companies increasingly need to ask why sustained presence is necessary, whether another mobility model could accomplish the same objective, what skills or knowledge are expected to be transferred and what happens when the employee returns.

That fits with a broader change identified by LARM’s 2026 global mobility trends report: companies are expanding beyond a single expatriate model toward more flexible portfolios that include short-term, rotational, commuter, virtual and permanent-transfer options. The future, then, is not a choice between traditional expatriate assignments and alternative mobility.

Companies are building portfolios in which each option serves a different purpose. Long-term assignments will remain important where businesses need deep market knowledge, sustained leadership, technical transfer or the development of global executives.

What is disappearing is the assumption that a fully loaded three-year expatriate package should be the automatic answer whenever talent needs to cross a border.
