ICE agents are given a bonus of $50k over 5 years, roughly 10k a year. There is a clause in their contract that if they leave they have to pay back that bonus. There is zero likelihood ICE lasts with this budget for 5 years so there will be a downsizing to fit the available money.
ICE agents in New Jersey will be unable to find a job to pay back the federal government the (at least) $20k and be debt trapped in the system they are trying to protect. It's some justice.
