Local reports suggest that the decline was largely driven by government attempts to deport illegal migrants, who live and work in the oil-rich Middle Eastern state without correct visas, as well as those who are involved in criminal activity.
Raids in areas popular with expats have become increasingly common. Earlier this week, over 700 foreigners who were allegedly violating Kuwaiti laws were seized in an industrial area to the south of Al Jahra city.
There are many bogus companies that are trafficking workers, thereby spoiling Kuwait's reputation... This is one of the reasons why raids are being held, to reduce the number of marginal laborers, an official told The Kuwait Times.
Like many Gulf states, Kuwait is dependent on foreign labour to plug gaps in its growing economy, with workers taking jobs in various sectors from construction to the resources industry.
The majority of these immigrants are poor workers from elsewhere in Asia, such as India, the Philippines and Pakistan, though there is also a large Egyptian population. Around two-thirds of Kuwait's 2.6 million inhabitants are believed to be from abroad.
