You can renew up to 12 months after expiration and still meet the criteria for renewal (4 hour class and range proficiency). Your CHL-100 will be good for 6 months after completion.

I would advise going to the DPS website and begin the renewal process right now. You will then be notified as to whether you will need to resubmit fingerprints and/or photos).

They're trying to reuse both as much as possible, but some marginal fingerprints are causing problems with the new electronic/scanned formats.

That 1-hr class mentoned above is for a Virginia CHL, not Texas.

It's far easier to begin the process online through the DPS than to go the other direction--but you can go either way, and even go with a full paper submission if you prefer...but either method is slower than online-registration first.
