Foreign workers are individuals who travel to a different country to take up employment. They often fill jobs in various sectors, such as agriculture, construction, and healthcare, where there may be a shortage of local labor. These workers can come from diverse backgrounds and may have different skills and qualifications. Many countries have specific visa programs to allow foreign workers to enter and work legally. This can benefit both the workers, who seek better opportunities, and the host country, which gains a workforce that supports its economy. However, the treatment and rights of foreign workers can vary significantly across different regions.
