I heard specifically from Govt oil and gas as THEY ISSUED NOC RELEASE BUT INTERNALLY they informed to immigration to not allow further change of RP. My many friends has told me same. In this way employee will become sandwich between 2 giants. However in cases my friends are sitting without paying salerise if this is the case don't stay more and to move quickly to safe money. As you spend here one month from your own pocket will more than you spend in your country for 6 months.
