Final answer:
Most immigrants to the U.S. currently originate from Latin America and Asia, with immigration from Europe declining in recent years.
Step-by-step explanation:
Based on current trends, the majority of immigrants to the U.S. originate from Latin America and Asia. In the past century, immigration from Europe has declined, while immigration from Asia and Latin America has grown substantially. By the 2000s, about half of U.S. immigration came from the rest of the Americas, especially Mexico, and about a quarter came from various countries in Asia.
