Just FYI: Went to the embassy in KL this morning to get my new Non-B. For anyone it may concern, every counter now has a poster that says that onwards travel tickets and hotel bookings are mandatory when applying for tourist visas.
TLDR : Answer Summary
A user reported that at the Thai embassy in Kuala Lumpur, new requirements for applying for tourist visas include mandatory onward travel tickets and hotel bookings. There are inquiries regarding the specific number of days required for hotel bookings, and clarification was sought on the timeline for onward travel tickets related to different visa types.
