With the closing or downsizing of many foreign firms, it is relatively easy to find qualified employees, though salaries are very low by Western standards. Salary caps, which the government implements in an apparent attempt to prevent firms from circumventing restrictions on withdrawal of cash from banks, prevent many foreign firms from paying their workers as much as they would like. Labor market regulations in Uzbekistan are similar to those of the Soviet Union, with all rights guaranteed but some rights unobserved. Unemployment is a growing problem, and the number of people looking for jobs in Russia, Kazakhstan, and Southeast Asia is increasing each year. Uzbekistan's Ministry of Labor does not publish information on Uzbek citizens working abroad, but Russia's Federal Migration Service reports 2.5 million Uzbek migrant workers in Russia. There are also indications of up to 1 million Uzbek migrants working illegally in Kazakhstan. Uzbekistan's migrant workers may thus be around 3.5-4 million people, or a staggering 25% of its labor force of 14.8 million. The U.S. Department of State also estimates that between three and five million Uzbek citizens of working age live outside Uzbekistan.
