Germany's immigration policy violates human rights, Turkish President Abdullah Gul told German broadcaster ZDF on Saturday, two days before a planned visit to the country, dpa reported. He was specifically critical of a 2007 change to immigration law, which only gives a person in Turkey the automatic right to join a spouse in Germany if the potential immigrant can prove knowledge of the German language. "I find this policy wrong," said Gul, arguing that it ran counter to human rights standards. The comments came just a few days after Gul had called on Turkish migrants in Germany to learn the language, in an effort to integrate better. He repeated that sentiment Saturday for ZDF. Turkish Prime Minister Recep Tayyip Erdogan has repeatedly caused outrage in Germany by telling compatriots to preserve their Turkish identity, and teach their children Turkish before German. Gul is set to start a three-day visit to Germany on Monday. He plans to meet both German President Christian Wulff and Chancellor Angela Merkel.
