What is one similarity between ellis island and angel island?

Both islands were the main immigration stations in their respective coasts.

Explanation:

-Ellis Island is a small barren island located in the port of New York. In 1808 the Federal Government bought the island, assigning it to military uses. During the War of 1812 against the English, it was converted into a fort.

Later, and from the disposition of the president Benjamin Harrison in 1890, Ellis became the main customs of the city. Between 1892 and 1954 approximately 12 million passengers, who arrived in the United States through the port of New York, were inspected there, both legally and medically.

-Angel Island is the biggest island of the bay of San Francisco, in California. In the 19th century, after the incorporation of California into the United States, it was converted into a military defense post. Later, between 1910 and 1940, it was used as an immigration station for people from the Pacific Ocean, mainly from China.
