China's Ministry of Labour and Social Security says 150,000 expatriates were legally employed in the country last year. This is almost double figures from three years ago.
To be considered a legal hire, the worker must have a valid "Z" visa and accompanying work permit.
There are estimates that the total number of expatriates working in major cities like Shanghai and Beijing could be more than 500,000, with most deciding to instead carry "F" visas, which while illegal, do eliminate tax burdens on the worker and employer.
Local media report that a lack of talents to fill new positions is a major reason behind the influx of foreign professionals.
