Now for every renewal must watch a video, about 45 min, answer 4 or 5 questions at the end (or middle, can't remember) which are very obvious and in English. Link provided on DLT website and must do this at home on computer or mobile etc., at the end get screenshot or photo of QR code that appears. Valid for 6 months. They need this on the day going for renewal. Then the usual reaction test and taking photo is done. I heard in Phuket at least, can no longer watch this video at DLT, must do it beforehand...
But in Phuket last year they gave me an appointment of 1.5 month after I went to renew (5 year to 5 year renewal). But usually it's about 2 weeks, not sure why, and I even argued with the manager, but she said they change only if I bring a proof of flight ticket that I am leaving, then they change it, otherwise have to wait...! (I said I'm leaving, but they are getting smart...).
I think other offices are not like this, Phuket is a meyham, too many people, and they still want more to come...! 🤔
