I know the admins don't like TM30 questions, so I apologize in advance.
I'd like someone to share their experiences in Chaeng Watthana (Bangkok) before I go there myself. Disclaimer: I'm aware of the app/site but can't use it yet.
My questions: What is Chaeng Wattana like on a Monday morning, when hundreds of foreigners come back from a weekend trip? Are we really all expected to take at least half a day off on Monday to re-register after a weekend away from Bangkok? How long will this take in reality? Not looking for complaints or speculations, just experiences so I can prepare myself as this will have major implications on my work life and planning.
TLDR : Answer Summary
The Chaeng Watthana immigration office in Bangkok can be quite busy on a Monday morning, especially following a weekend when many foreigners return to re-register. One user shared their experience of arriving early and still facing long wait times, indicating it could take several hours to complete the registration process. They noted that the queues build up quickly, and despite arriving at 5 AM, they witnessed the chaos unfold as many others came in afterward. Overall, it seems advisable to allocate at least half a day for this process, factoring in potential delays.
