10 Countries with the Highest Proportion of Immigrants

7. Oman 

Percentage Of Residents Born in A Foreign Country: 46.5%

Oman is historically a nation of immigrants with a significant expatriate population. As of now, expatriates represent 46.5% of Oman’s total population because of its need for skilled and unskilled labor. Despite their significant presence, immigrants in Oman have faced challenges. Like Saudi Arabia, the sponsorship system called “kafala” ties migrant workers’ legal status to their employers and can lead to instances of exploitation.
