If you are married, unless you are legally separated (i.e., there is a written agreement recognized by a court or a court order), you need to include your spouse as well even if he/she does reside with you and/or will not immigrate with you. Of course, if you are legally divorced or widowed, you no longer have a spouse and you don't have to enter the former spouse information.
The structure of the draw is one which regular lottery players will be very familiar with; players must pick 5 regular numbers from a pool with a total of 69 numbers and in addition to these regular number picks, you also choose one bonus ball (known as the Powerball) from a pool of 26. These two pools of numbers are mutually exclusive and remain completely separate throughout the drawing procedure. In order to jackpot the US Powerball, you need to match all 5 regular numbers and the Powerball. Do this and you are instant Powerball millionaire – it’s as simple as that!
