Why do Thai embassies request documentation I've already submitted for my visa application?

Two applications I was involved with received requests for further documentation that it could be said had been supplied already; 1. Work contract

2. Bank statement showing the minimum 500k

What was then uploaded was 1. The work contract again, plus another letter from the person’s line manager, dated on the day of the request for further documentation, with more specific information regarding the terms of the DTV rather than the original, more generic ‘this person can work remotely from Thailand’.

2. Bank statement dated on the day of the request for more documentation as we assumed they wanted to check that the money was still there.

The requests they send have these generic descriptions but I think that if they’re asking for something you think you’ve already sent, it may well be that what you’ve already sent might not quite be what they’re looking for.

When I help online visa applications (which ate not just for Thailand) I always try to imagine the person looking at the application, what their criteria are, and that all they have to go from is what you’ve uploaded. So try to make what you’ve uploaded as comprehensive as possible so that they can them approve your application and move on to the next one.

If they ask you for a specific document, I suggest you to send back that one alone. Even if you already sent it previously in the package.

The visa application is digital. Ask them to check the record again.
