Each year, millions of people from countries around the world immigrate to the United States, ranging from tourists visiting for a couple of weeks to workers coming for a job to refugees escaping persecution. The number of people coming to the US, where they come from, and why they come has changed significantly over time.
The reasons why people immigrate to the US have changed in recent years. In 2015, 987,894 student visas were issued. That figure fell 27.6% to 714,885 in 2018. During the same period, the number of work visas — including both skilled and unskilled workers — increased 16.4% from 762,473 to 887,528.
