Hello, my name is Mariano. *For as long as I have lived in the US, I have believed I was a citizen by naturalization. My parents 5 old me they completed all the steps when I was a child. *However, recently, my brother was notified that his record did not indicate that he was a citizen which also means I'm probably not either. *It is our understanding that we just need to take an oath for citizenship. I have a US passport if that helps. How can I verify that this is all I need to do? *
