it's so sad to think that you will be separated again with your kids... but try to negotiate again with the labor officers. A friend of mine has the same flight with yours. She go to ministry of labor with the complete documents and attached letter in arabic explaining their situtations and begging for consideration, and the officers consider their application. After she receive the receipt the next day the children has the visa number.. Cheer up! There still some way and there's no impossible in prayer.
