Gastarbeiter (German for 'guest worker'; pronounced [ˈɡastˌʔaʁbaɪtɐ] ; both singular and plural) are foreign or migrant workers, particularly those who had moved to West Germany between 1955 and 1973, seeking work as part of a formal guest worker program (Gastarbeiterprogramm). As a result, guestworkers are generally considered temporary migrants because their residency in the country of immigration is not yet determined to be permanent.[1]: 87 Other countries had similar programs: in the Netherlands and Belgium it was called the gastarbeider program; in Sweden, Denmark and Norway it was called arbetskraftsinvandring (workforce-immigration); and in East Germany such workers were called Vertragsarbeiter. The term that was used during the Nazi era was Fremdarbeiter (German for 'foreign worker').[2] However, the latter term had negative connotations, and was no longer used after World War II.
The term is widely used in Russia (Russian: гастарбайтер, gastarbayter) to refer to foreign workers from post-USSR or third-world countries.[3][4]
