Would-be immigrants stand behind a fence in a camp for illegal migrants in Mukachevo, a small town in western Ukraine, just a few dozen miles from the border with Slovakia, Hungary, Poland and Romania in this May 29, 2008 file photo. In this former army barracks close to Mukachevo, Europe's immigration debate comes to life in the men who paid between $6,000 and $15,000 to smugglers to take them out of their often turbulent countries. But their dreams of starting a new life in the rich 27-member European Union, by sneaking across Ukraine's border with four EU states, have been dashed. Now, bored and frustrated, many are just waiting for the chance to try again. To match feature UKRAINE-MIGRANTS/ REUTERS/Gleb Garanich (UKRAINE)
