Hi Platinumsweet,
The proposal of salary cap to AED 10,000 for sponsoring families are under National Council review and it will be implemented soon, not in a couple of months but most likely within 6 -12 months.
Majority of the expatriates are against this move, even though current AED 4000 limit is too low, the proposed AED 10,000 is too high either. May be AED 7000 would be more reasonable figure, because at least that much money would be required to maintain a family in UAE.
Interestingly, there is a recent development from Lieutenant General Dahi Khalfan Tamim, Dubai Police Chief, who said the sponsorship system should be abolished as it burdens Emiratis with unnecessary responsibilities. Widely opposed by the Business Leaders.
