Is there anything to prevent him from moving to a country without a US extradition treaty in the meantime? That seems like a pretty big risk of waiting too long.
Make a list of the countries that don't have an extradition treaty.
Then cross off the countries that have people you screwed or governments that might find it politically advantageous to prosecute you. And then cross off the countries that might send you back even without an extradition treaty.
And then cross off countries that have worse internet than prison.
