Alien Self Deport
The name, self deport, says it all. Any alien who has received an order of removal may choose to self deport and remove themselves from the country before ICE issues a surrender demand.
A self deport does not avoid the effects of any order issued by an immigration judge (e.g., a 10-year ban on being admitted to the United States). If the alien provides proof of their self deport (e.g., a notarized statement from an officer at a United States embassy or consulate), however, the surety will be able to obtain cancellation of the delivery bond.
