The specific release date should be printed on the parole papers your husband received. That document is the most reliable source for the exact timeline, so the first thing to do is look there for a date.
Beyond what the papers say, there is typically a processing lag between when parole is approved and when the inmate actually walks out. That window generally runs somewhere between 60 and 120 days from the time the notice is received. The variation depends on how quickly the parole board's administrative process moves, whether all the release conditions have been formally confirmed, and how the facility processes outgoing inmates.
The address approval your husband received is a significant piece of the puzzle. It means the proposed residence has been investigated and cleared by the parole officer, which removes one of the more common causes of delay. When a home plan gets approved alongside the parole papers, the path to release is considerably cleaner than situations where the address is still under review.
During this window, the most important thing is that your husband does absolutely nothing to jeopardize the approval. An incident report, a disciplinary issue, or any conduct that raises a red flag this close to release can delay or in serious cases revoke a parole grant. This is the time to be the most disciplined and low-profile he has been throughout the entire sentence.
Start preparing for his return now. Know the conditions of his parole, have a plan for reporting to his parole officer on the first day, and make sure the approved residence is ready. The 60 to 120 day window moves faster than it feels right now.
