“That’s right, because the term “citizen” includes naturalized citizens
And when did that take place? Within the Constitution? Or, years after?

At the time the Constitution was adopted, as far as the Constitution of the United States is concerned, there were two kinds of citizens. “Citizen” as mentioned in the Constitution, and “Natural Born Citizen” as mentioned in the Constitution. There was no “Naturalized” Citizen of the United States till years later.

Well until two years later. The Constitution was ratified in June of 1788 and the first Naturalization Law was passed in March of 1790. The Naturalization Act of 1790 limited naturalized US citizenship to aliens who were free white persons of good moral character. Therefore white indentured servants, slaves, American Indians, and free blacks could not become naturalized US citizens.

Correct. As previously stated, the Constitution mentions two types of citizens, and only two.
