The actual answer btw is that you can’t revoke anyones citizenship if they were born in the u.s. It’s actually kinda interesting and goes back to slavery and the dred scott decision, where the supreme court ruled that slaves and their decedents couldn’t be citizens. In response, after the civil war when they were drafting the 14th amendment they added the “citizenship clause” which granted automatic citizenship to everyone born in the united states. So basically because the point of this amendment was to give certain people citizenship regardless of what congress or the government say, the supreme court later ruled in Afroyim v Rusk that congress can’t revoke the citizenship of anyone born in the us. Although, interestingly, the court later ruled in Rogers v. Bellei that congress could revoke the citizenship of someone born outside the us to american parents since that citizenship doesn’t come from the citizenship clause
