Generally speaking, there are several agencies in the Dallas-Fort Worth area hiring and most if not all are more than willing to look at out of state lateral candidates. Including the largest agencies such as Dallas or Fort Worth PD. Most of the departments may want you to complete a full or modified academy to obtain you peace officer's license but you'll have to check with any department you have an interest in to find out what they may specifically require.
