What are the ways to effectively contact the Thai Embassy in Phnom Penh regarding a pending DTV visa application?

What's your history of entering Thailand this year?

I would suggest extending your visa. I did it a few years ago in PP through an agency. They asked for 150usd though because I only had a few days left.

I also applied DTV visa on October 5 in Cambodia. I just got approval email on November 20.

I had been waited for 46 days in total since the day I submitted.

I just stayed in Cambodia until Nov 9 as my Cambodia visa is expired. Then I just returned to my country and waited for the approval email. But still didn’t get any response from embassy until Nov 19.

On Nov 20, I just sent follow up message to Thai Embassy in Phenom Penh via Line Account. I got approval email 2hrs later after I sent follow up message.

Sending email to them is not working. They didn’t any reply on email.

If you want to follow up to them, I just want you to advise to send message via Line Account or call directly on phone.

You could try Facebook Messenger but whether you get them or not you need to stay in Cambodia until the process completes. Do not return to Thailand

From what others who applied in Cambodia have reported, it takes on average a month to get an answer.

Looks like going to be rejected

My gf did on October 10th and still waiting. Unlikely that you will have it soon unfortunately. If you are in PP you can extend your visa or go in another country, in the rest of the country you can extend with agency but it takes longer to extend as they have to send everything to PP.

Good luck as 6 weeks and still waiting on our side...
