1. Saudi Arabia
We came to the country which definitely has the biggest number of legal immigrants, or in other words 32.3% of their entire population. Why Saudi Arabia? Apparently, this country is the most popular for workers from Pakistan and India, but also some other countries such as Egypt, Yemen, Sri Lanka, Bangladesh and many others. There is a long history of accepting foreign workers because of the simple fact, known as cheap labor. On the other side, there are also many illegal immigrants who come to Saudi Arabia mostly because of work, and it has been estimated that only the number of Pakistani unregistered workers reached 40,000. The fact that there are many other people who seek refuge in Saudi Arabia, especially coming from Muslim countries, brought it to the first place of the list of the countries that have the most legal and illegal immigrants.
