WATCH: Nearly half of Arab youth want out of their home countries, poll finds

Young immigrants leave from the train station of Nea Vissa in the Evros region about 1,000 kilometers (600 miles) northeast of Athens, on Monday, Oct. 4, 2010. According to European Union figures, some 90 percent of all people caught trying to enter the 27-member union illegally are caught on the borders of debt-ridden Greece. Less than four kilometers from Greece's porous land border with Turkey, the village of Nea Vissa is the first main gathering point for the thousands of migrants from Asia, Africa and the Middle East who enter the country illegally every year. Once there, typically the migrants will wait for a police bus to pick them up and take them to a nearby detention center, where they will be fingerprinted, given one-month residence permits and released _ usually gravitating to Athens. Police say more than 23,000 immigrants crossed the Greek-Turkish borders in the Evros region during the first eight months of 2010. Although many apply for protected refugee status, Greek authorities accept less than one percent of all applications. (AP Photo/Alkis Konstantinidis)
