When did Yugoslavians immigrate to the US?

There are two major waves of Yugoslav immigration to the United States:

1. The first wave occurred between 1890 and 1914. During this time, approximately 250,000 Yugoslavs immigrated to the United States, mainly from Croatia, Slovenia, and Bosnia and Herzegovina. They were primarily farmers, laborers, and miners, and they settled mostly in the Midwest and the Western United States.

2. The second wave occurred after World War II. During this time, approximately 500,000 Yugoslavs immigrated to the United States, mainly from Serbia, Croatia, and Bosnia and Herzegovina. They were refugees from the war and political turmoil in Yugoslavia. Many of them were professionals, such as doctors, engineers, and teachers. They settled across the country, with large populations in Chicago, Los Angeles, New York City, and Pittsburgh.
