European Union
The European Union has a different definition of "foreign national."  In the European Union, a person is only thought of as a foreign national if they are not a citizen of any country in the European Union.  These people are called "third party nationals," not "foreign nationals."

 The United States 

The United States Department of Homeland Security says that a foreign national as a person "who is a citizen of any country other than the United States."

In other words, a foreign national is a person who:
 Was born outside the United States; and
 Is a citizen of another country; and
 Has not become a United States citizen through naturalization.
