The EU is already making it easier to suspend visa-free travel before it grants such right to more states, most notably Turkey, whose help it needs to control immigration after some 1.3 million people reached Europe last year. While Brussels says Turkey, with a population of 79 million, is making progress on 72 criteria to win the EU visa waiver, Ankara is seen missing an end-June deadline.
