Brit: Usually, this is how it all begins. First, one GCC country takes the step and if they succeed, others follow. It happened several years back when the UAE started a process of granting a grace period to all illegal foreign workers to leave the country warning even the people housing them of penalties and jail terms should any one get caught after the grace period expires. Thousands left. When Saudi Arabia saw the effects of this action, they too went ahead and took this step. A person in my neighbourhood I know who was staying illegally in the Kingdom for 14 years, also fled.
