Driver license renewal what to use? - EAD or GC?

[pvkprasad]

Not as important as the immigration topic , I still have a question and seek inputs from anyone who might have already encountered and found a solution

My wife and kids got their GC EAD in Sep 2021 and they are using it for jobs they took after approval

My wife and minor son had a pending H4 application as their prior H4 expired in July and it got approved in November.

My son passed his driver road test and will be going to DMV for the actual driver license next week (we are Houston TX btw )

For the proof of legal stay in US can he use the H4 approval to get a longer duration for his DL or should he only use the GC EAD?

Given a choice getting the license for longer duration makes sense - I just want to make sure I am not presenting the wrong document to DMV to land in trouble at a later date
