Will my travel to Sri Lanka affect my Thailand visa application processing?

Just send an email to the thai embassy in sri lanks seeking a clarification

1. You got to stay in the country where you are during the application time, time is probably to short 2. There is a big chance that the time is to short 3. You could apply for anew visa in Sri Lanka where the other will be canceled or need to be cancelled but your time will again probably to short High season you can count on average 4 weeks from application till approval Do you need a visum for Thailand? Is your passport not legible for visa exempt? With visa exempt you can have 30 days of stay in Thailand , which can be extended by another 30 days in local immigration. If you want the extension you shall have to show Sri Lanka check-in an outbound ticket after 30 days in Thailand, (you can buy any cheap outbound ticket in advance what you are not gone use)

How long is your stay in Thailand? It makes a difference

1. No

2. Yes - if you have shown flight details from SL to BKK , they would be aware

3. Once a Visa is paid for

nothing can be changed or cancelled, you would need to apply again if you wanted to .

Particularly this year they are just slow and they seem to approve Visa’s closer to the date one flies out

I hope you get your visa on time, we applied 5th October and we are still waiting🥲

You are definitely cutting it too close with those dates…
