Texas doesn't allow concealed carry without a permit. If you are a resident of those states that allow CHL without a permit, you'll have to get a permit to carry in Texas. Texas also also doesn't recognize Utah's CHL's due to their lax criteria. Representative Todd Hunter will sponsor legislation in 2013 to allow open carry by CHL holders.
Twice now you have posted that Texas doesn’t recognize Utah carry permits.
They most certainly do.

They even recognize South Dakota’s which has no requirements at all, except pay your $10 and pass the background check. (I have one.)
