When should I apply for a DTV visa for Thailand and are there any travel deadlines after approval?

The user is looking for guidance on applying for a DTV visa from the UK for travel to Thailand in late September 2025. They inquire about the appropriate timing for their application and whether there is a need to enter Thailand within 90 days of visa approval. Commenters advise applying two months before intended travel and clarify that while there's no strict 90-day rule, applications made more than 90 days prior to the travel date may not be granted.
