Witness Protection Program questions

When one joins, what is given to them once they do their part in court? For instance, do they get a house? Is it free or do they have to get a job and make payments eventually? Are they given a car? Payments? See where I’m going?
Thanks.

They are given a new identity and location. They are provided with secure transport to and from the courthouse by the US Marshall’s Service. Depending on circumstances, they may get a small stipend for a time. Gainful employment and housing is the responsibility of the witness.
