How can I find out if I'm a U.S. Citizen already without having to pay for a lawyer or other to search for the info?

OK, where you born in the US? Was one of your parents a US citizen,

Or did you apply for citizenship and take a oath to become a citizen.

If you are a citizen you would or should no it.
