Unfortunately, you will not be able to vote in Collin County in the election you appeared to vote in. You will be instructed to attend your designated polling location in the county you now live in to vote provisionally. The best way to avoid this scenario is to update your voter registration immediately when you move into a new county. If you are unsure if you are registered in your county, or registered at all, make sure you complete this process 30 days before any election you plan to vote in.
