Hi @phoog, I figured I should stop spamming the comments. Sorry to drag you in here, feel very free to ignore me or just answer when/if you have the time.
Are you sure about that example you mentioned? A child who is eligible for US citizenship will automatically be considered a citizen?
That seems very strange to me.
So if the child were to grow up without ever having taken any steps to acquire citizenship, the IRS could then hound them for taxes?
