Although this DTV is new, if you have a current extension of stay (rather than an actual visa) it would make sense, if your DTV is approved, to go to immigration upon your return to Thailand and cancel it.
Although having said that, it would be interesting to see what they stamp you in on at the Thai border seeing as you have an active re-entry permit.
If you’re planning on being in Thailand on the DTV for the foreseeable future then best to cancel any extensions immigration have given you.
you may well see them as the same as cash., and they may well be the same as cash. However, what matters in the visa process is what the embassy requirements are for evidence of funds.
My point was, as a person who has successfully applied for, and helped others app,y for visas from the Thai embassy in London and the uk embassy in Thailand on many occasions, often what we regard as sufficient evidence isn’t seen that way by the people processing the application.
So you can be as adamant as you wish about the nature of your financial evidence but if it doesn’t meet their criteria, they will refuse your application on those grounds.
Rather than look for another category to apply under, maybe you can analyse why your application failed. Perhaps some of the evidence was not acceptable. Your financial evidence, your company evidence.
Because if you apply again under a different category and the thing that was wrong is still wrong, you’ll get rejected again.
