True, but Saudi Arabia treats all 'foreign workers' as guest workers.  Since the Saudi economy has taken a downturn, it has been deporting foreign workers. 39,000 Pakistanis were deported in the past four months alone, but thousands of workers from the Philippines, Ethiopia, Yemen and other nations are being deported because there are no jobs for them anymore.  Saudi Arabia has no 'social assistance' programs to maintain unemployed workers, and it NEVER signed the UN Convention on Refugees when it became a member state of the UN. Similarly, India, Pakistan, Indonesia and Thailand are NOT signatories, nor are the Gulf States. With the UNHCR claiming there were 65-million refugees as of Oct 2016, up from 45.2-million on Oct 2014, the 1951 Convention (designed for much smaller numbers) is failing and needs revision. Instead of spending $billions on refugee transportation, assessment & hearings, while trying to stop people-smuggling, programs must be supported in 'refugee homelands'.
