PIP: The legal dispositions governing Turkish immigration to European countries, the imperfect success of European efforts to discourage immigration, and factors in the elevated potential for continuing Turkish emigration are examined in this article. Turkey's 1963 5-year plan clearly revealed the government's intention to utilize external assistance to finance development efforts, while depending on labor migration to European countries to absorb surplus labor and provide remittances to ease the chronic balance of payments deficit. The Turkish government viewed with satisfaction the adoption in the 1963 Ankara Accord (a preliminary document in Turkey's quest for European Community membership) of articles concerning free circulation of workers, but the dispositions were never put into practice. The termination of immigration by the European countries in 1973-74 initially appeared to be a temporary response to the petroleum crisis and worldwide recession, but the measure became permanent policy, contributing to the deterioration of Turkish-European relations. Because of its internal policies of repression of minorities, sharp regional and ethnic disparities in development and income, and continuing high rate of population growth, Turkey has a very strong potential for further emigration. Some 4 million Turks constitute the largest foreign group in Europe. Immigration control measures have slowed entry of workers, but they have not prevented immigration for family regrouping or influx of refugees seeking asylum.
