Migrant worker
person who migrates to pursue work

A migrant worker is a person who migrates within a home country or outside it to pursue work. Migrant workers usually do not have an intention to stay permanently in the country or region in which they work.
Migrant workers who work outside their home nation are also known as foreign workers. They may also be called expatriates or guest workers, especially when they have been sent for or invited to work in the host country before leaving the home country.
The International Labour Organization estimated in 2019 that there were 169 million international migrants worldwide. Some countries have millions of migrant workers. Some migrant workers are illegal immigrants or slaves.
Definition
The International Organization for Migration's Global Migration Data Analysis Centre states that "there is no internationally accepted statistical definition of labour migration", but refers to the International Labour Organization (ILO)'s definition: "international migrants who are currently employed or unemployed and seeking employment in their present country of residence".
Worldwide
An estimated 14 million foreign workers live in the United States, which draws most of its immigrants from Mexico, including 4 or 5 million illegal workers. It is estimated that around 5 million foreign workers live in northwestern Europe, half-a-million in Japan, and 5 million in Saudi Arabia.
This brief starts where responsible research should: with the source description of “Migrant worker” as person who migrates to pursue work. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as person who migrates to pursue work. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Sep 10, 2026. The linked authority identifier is Q15320003. The Library of Congress control number is sh85085067. 1 of 1 selected statements include explicit references; 1 carry qualifiers and 0 use preferred rank. The first chronological checks are 2019.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
