of course you don't need a Thai bank account for getting a visa to Thailand when applying abroad. That would be impossible and totally stupid. Another type of visa you say - visa exempt is not a visa if that's what you talk about.
that won't happen! The uploaded files are rejected immediately by the system if they can't be read or not approved and then you just do it again until they are accepted and continue with your application
sorry Carlsson but for your information - if you are interested - it is know (present tense) not knews - that word doesn't exist. He knows - they know. It's not a typo since o and e are on the opposite side of the keyboard.
