? Is his visa now out date he want to return April 2020
TLDR : Answer Summary
The TM7 visa, an Extension of Stay from the Immigration Office, likely expired after your brother left Thailand in December 2018. To return for a longer stay, he will need to apply for a new visa at a Thai Embassy before his arrival.
