I applied for naturalization and have been approved for U.S. citizenship. My swearing-in ceremony is scheduled for next month. I understand that, as a U.S. citizen, I will be able to apply for a U.S. passport. But what does that mean for my old passport? Do I need to give it up? I am reading the citizenship oath, and it says that I must promise to “renounce and abjure all allegiance and fidelity to any foreign prince, potentate, state, or sovereignty, of whom or which I have heretofore been a subject or citizen.” To me, that sounds very much like I will be asked to give up my old passport, as well. What should I expect?
