I was issued a DTV on the 13th of May with the intention of entering Thailand (and starting the Muay Thai course for which it is intended) in late June.

However, due to family concerns, my plans have changed and I may not be able to enter Thailand until late August. Even though the visa doesn’t explicitly say so, I’m worried that this may cause it to be nullified as it is more than 90 days from the date of issue.

Should I be worried about this? Many thanks.
