What agencies can assist with switching from a DTV visa to a Non-B visa and obtaining a work permit in Thailand?

That happened to me too. I applied the 2nd time and had to keep trying to change the passport expiry date. I got it in the end

Why did you go to the Embassy ? Why didn't you apply online at the Thai E-visa site ?

You're implying that someone between you and Thai Immigration messed up.

I mean, the Embassy would just take your docs and submit them, no ? Or would they have transcribed the details somewhere/somehow and forwarded on the paperwork ?

The application website uses OCR optical character recognition to read the biodata page photo of your passport after it's uploaded. The OCR is notorious for misreading the information. The e-visa website specifically warns you to check the integrity of the data filled in automatically. After you upload the photo you must triple check the form before submission.

use your phone, video as u do it (or something like that)....

Just look at your screen shots of each step of the application. You can then use these to prove that you entered the right information. Best of luck.

I recall there are warnings about getting these details correct as they cannot be changed. I applied through Canberra and was very careful. This is Thai Bureaucracy for you. I am now in Thailand and went to get 4 Certificate of Residence certs. ฿500 baht each but my GF wanted to save me money so talked on the phone to the IO. Next thing I know the IO says you can come in three days time and get free one, is this what you want. I am like sure I can come back in 3 days and save ฿2000. So I agree, I sense she is annoyed as she already made the 4 certs, handed them to me but then asked for them back.

She started peeling my photos off the certs and said you come Friday and get one free. You then come in three more days and get next one free. Have to go 5 times to get 4 CoR for free. No time to think about any middle ground but so go back on Friday and I will get one free, pay for one immediate one then apply for one in another 3 days so I will pay ฿1000 for 4. Keep frugal girlfriend happy and only attend 3 times to collect what I did have in my hot little hands just yesterday.

Same with airline, they can refuse you at checkin if name is spelt wrong

you can check your documents through the same online portal you applied

I applied in Canberra. They told me I had not uploaded a document which I had uploaded and was attached to my application. I uploaded the same document and it was approved???
