How do I prove my accommodation in Thailand while applying for my DTV in Hanoi?

When applying for a DTV visa in Hanoi, it's generally not necessary to provide detailed proof of where you will be staying in Thailand. Most commenters suggest that as long as you have the required documents for the application, you can simply fill in the address of your accommodation. One user shared their experience of including a letter from their family member along with a photo and scans of their passport, which contributed to their application being processed quickly. Overall, the emphasis is on ensuring all required documentation is submitted.
