Переведите и ответьте на вопросы Some of these changes have been brought about by changes in the immigration laws. Until the 1850s, immigration to the U.S. had been largely unrestricted, with some 90 percent of all immigrants coming from Europe. In the 1920s, a number of measures were taken to limit immigration, especially from Asian countries and southern and eastern Europe. The overall number of immigrants was limited by law and quotas were set for countries and, later, "hemispheres." In 1968, this quota system was abolished. An annual limit of 170,000 was set for immigrants from the Eastern Hemisphere and 120,000 for the Western Hemisphere. Ten years later, the separate limits for the two hemispheres were abolished in favor of a worldwide limit of 290,000 per year. In addition, however, special measures were taken to allow large numbers of refugees from several regions (especially East Asia and Central and South America) to enter the U.S. Thus, the average number of immigrants legally admitted throughout the 1970s was about 430,000 per year. The number jumped to 654,000 in 1980, reflecting a new wave of Cuban refugees. In recent years, the number of immigrants officially admitted to the U.S. was around 550,000 per year. 1.
