I used QMS app. 6 am sharp, queue number opens. I renewed back in April. No online, just walk in. I battled and got number 5 on the app. 8am I arrived in UTC Sentul KL. By 10am I got my passport already.

I checked the app again today and see that more immigration centres are added to the app. I hope one day all centres are available on the app. I loved it, no need to queue from 6am at the immigration office, can battle from anywhere.
