revoke her citizenship - The oath she take when she becomes a citizen states: “I hereby declare, on oath, that I absolutely and entirely 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...”
If she isn’t following the oath and puts Somalia first then rescind her citizenship and she can go back to where she came.
Somalia was the one a few articles down. This one claims allegiance to Sudan.
I know, hard to keep track these days...
