Going to apply in Hanoi next months.
Besides the basic required documents I will provide an dental implant treatment schedule with 2 past and 4 future appointments until the end of 2025 including receipts with my passport number and dentist registration number,an rental agreement in Thailand and a hotel booking in Hanoi.
Would this be a probable reason and documentation?
Any experience members done this already.
TLDR : Answer Summary
The original poster plans to apply for a visa in Hanoi and intends to provide a dental treatment schedule along with other documents like a rental agreement and hotel booking. Community members suggest contacting the embassy directly due to varying requirements and mention others' experiences with similar appointments successfully securing visas.
