What is the difference between immigration and expatriation?

Immigration and expatriation are two terms often used to define international relocation. However, they actually refer to different situations with different legal, social and cultural implications. Magellan gives you an insight into the fundamental differences between these two concepts, highlighting their main characteristics, motivations and consequences.

Defining immigration and expatriation

Immigration and expatriation are two distinct forms of international relocation with quite interesting nuances.


Immigration refers to the permanent or semi-permanent movement of individuals from one country to another with the intention of settling permanently in the host country. It usually involves a permanent change of residence motivated by various factors, including economic and career opportunities, safety, or the quest for a better quality of life. For example, an individual relocating permanently to the United States in the hope of a better life illustrates immigration.


Expatriation refers to a person’s temporary move to a foreign country for work, study, or other professional commitments, with the firm intention of eventually returning to their home country. Unlike immigration, which often involves a permanent change of residence, expatriation is generally temporary, with a defined duration of stay. For example, an executive transferred to Mauritius by their company to manage a subsidiary for a few years, and having to return at the end of their assignment illustrates the concept of expatriation.

Motivations for moving abroad

The motivations for moving abroad can be very different in the contexts of immigration and expatriation. In general, immigrants are people seeking better career and economic prospects, a better quality of life, safety, or political stability, while expatriates are usually transferred overseas by their company to fill a specific position or people who choose to work abroad to gain international work experience.

Duration of stay

One significant difference between immigration and expatriation is the duration of stay. Immigrants generally settle permanently in their host country, while expatriates know right from the start that it’s going to be a temporary stay, usually for a few years, before returning to their home country.

What is the ideal duration of expatriation?

Is there really an ideal duration of stay in a foreign country? Rather than looking for a universal definition of “ideal” duration, let’s have a look at the pros and cons of different durations, ranging from short-term (2 to 12 months) to long-term (more than 5 years).

Short-term expatriation (2 to 12 months): This provides an individual with an international experience without a long-term commitment, making it easier to discover a new culture without the complexities of long-term expatriation. However, this may not be enough to allow full integration.

Intermediate expatriation (1 to 5 years): This duration offers a good balance, allowing an individual to thoroughly understand local life and integrate while maintaining links with the home country. However, it may be difficult for one to achieve particular objectives, such as buying a home.

Long-term expatriation (over 5 years): This gives an individual enough time to fully integrate into local life, realize ambitious personal and professional projects, and even consider staying permanently. However, this requires a lot of preparation and sometimes complex administrative procedures.

Administrative status

An immigrant often has to obtain legal status in the host country, such as permanent residency, with the possibility of acquiring citizenship over time and under certain conditions. Expatriates, on the other hand, generally remain temporary residents of their host country, and their legal status generally depends on their employment contract or work visa.

The impact of immigration and expatriation on the economy

Immigration can significantly impact a country’s economy, contributing to demographic growth, the local workforce, and cultural diversity. On the other hand, expatriation usually benefits the home country’s economy through the transfer of skills and knowledge acquired abroad. What’s more, the professional and personal ties forged abroad can open up new opportunities for cooperation and partnership between local and international companies, strengthening trade and promoting long-term economic development.

Adaptation and reintegration

Immigrants often face challenges in adapting to their new country, such as learning a new language and understanding cultural norms. Expatriates may also find it difficult to adapt to their new environment, keeping in mind that they also have to reintegrate into their home country at the end of their assignment.

Family dynamics

Whether it’s immigration or expatriation, moving abroad plans can have a significant impact on family dynamics. Immigrants may choose to bring their family along to their new country, while expatriates may choose to move alone, leaving their family in their home country, although they also have the possibility of having their family join them on their new adventure.
