What are similarities between the treatment of immigrants in the US and the guest workers in Western Europe

Explanation:

guest worker program allows foreign workers to temporarily reside and work in a host country until a next round of workers is readily available to switch. Guest workers typically perform low or semi-skilled agricultural, industrial, or domestic labor in countries with workforce shortages, and they return home once their contract has expired.[1]

While migrant workers may move within a country to find labor, guest worker programs employ workers from areas outside of the host country.[2] Guest workers are not considered permanent immigrants due to the temporary nature of their contracts.
