RE: Colorado Pref. Pt.
You don't have to fill in the second choice with any thing. Just fill in the hunt code for your preference point, and yes you will have to send in the full amount of money of $254. When you apply for a point only, your money minus $3 app. fee will be refunded. You may also be charged another $25! SO, it will probably cost you $28 when all is said and done.
Look on pages 3 and 4 under preference points and preference point hunt code and you'll see all the criteria.
