A more thorough explanation:

Definition: A foreign state is a country that is not the one being discussed. It can also refer to a state within the United States that is different from the one being discussed.

Examples:

• When traveling to a foreign state, it is important to research the local customs and laws.
• The governor of California met with the ambassador of a foreign state to discuss trade relations.
• If you are from New York and discussing state laws, a foreign state would be any state other than New York, such as California or Texas.

The examples illustrate that a foreign state can refer to both a country outside of the United States and a state within the United States that is not the one being discussed. It is important to clarify which definition is being used in a given context.
