imigration problem

The United States of America is known as "The Land of Opportunietes". We know that this country has at least 10 millions of illegal emigrants.All these people came to this country for different reasons.Most of them for political,religious or economical reasons.Many immigrants are not here to become a citizens.Many wish to stay for short time and than return to their home.In fact many immigrants are reluctant to become legal.Many harbor hopes and dreems of returnig back to their friends and family back home.Some of them want to have "dual citizenship" to travel back and forth,but there are still many of them who want to stay and get their citizenships.I am curious when this will happen.Former president G.W.Busch had promissed to legalize ilegal imigrants,but after he was elected for second term nothing happend.For another four years of his presidency he did nothing for emigrants.Looks like he just use this immigration issue for his personal benefit to get voted for another four years.
