The International Religious Freedom Report 2007, of U.S. Department of State, estimated that more than 8 million foreigners are living and working in Saudi Arabia, including Muslims and non-Muslims. There are 400,000 Sri Lankans, as well as a few thousand Buddhist workers from East Asia, the majority of which are: Chinese, Vietnamese, and Taiwanese. There is also a possibility that a percentage of Nepalese immigrants also help make up the estimated 8 million foreign residents in Saudi Arabia.
