The character Mike Ross from the TV show "Suits" is sentenced to two years in prison but gets released early after serving approximately three months. His early release happens because he assists in solving a case involving insider trading while in prison, and he cooperates with the authorities, leading to a reduction of his sentence and parole after about three months served. This early release is depicted in Season 6 of "Suits" and is tied to Mike's legal skills and cooperation with prosecutors during his time in jail.

If the question refers to Mike Scofield from "Prison Break," he originally gets a five-year sentence, but the specific release date in the show's timeline is not directly mentioned in the sources available. The story revolves around his planned escape rather than a set prisoner release date.

Please confirm if the question refers to Mike Ross from "Suits" or Mike Scofield from "Prison Break" for more precise details.
