Overseas employment requires sacrificing far away from the family ,especially when you do not know the consequences of your arrival abroad,you have a lot of difficulties before you reach the life expetancy of your life,you endure the hard work for your loved ones family.
What is the problem for these authorities if the expat workers bring their families? I have seen that in most of the GCC nations (such as Qatar, Saudi Arabia and the United Arab Emirates), they don't allow the blue collar workers to bring their families. This in turn causes a lot of trouble, as these workers are able to visit their families only once every three or four years.
