It shouldn't be an issue, you might get questioned though. However... no one can say for sure as each IO is different and even then each person they see is different too.
Just make sure you have proof of accommodation, 20k in cash and a copy of your ticket out of thailand. If you really don't want to risk being denied you could always pay an agency like
that might be an issue with your phone or browser. Try clearing your cookies etc or a different browser. It could also even just be an issue with the website, they are notoriously known for not being very well made.
Regardless though, even on the very slim chance it is blocked, or there is an issue with the website, you have options Thai side, if worst comes to worst there are kiosks just before immigration you can do it on.
You do it in the airport on your phone or on one of the provided TDAC terminals before immigration. However I very much doubt China has blocked the TDAC website.
I know two people who've got a the DTV from Hanoi recently, one person it took 6 days the other it took 17 days as they had to upload more evidence and paperwork. However they were both going the work route not soft-power.
So in short, like everything, it will take as long as it takes. However I would very much suggest you stay in the country as I know someone who went to Taipei last year, they were called in for an interview and had gone back to Thailand. Visa application got cancelled.
Getting his passport and/or ID card will make him eligible for military conscription. And despite what people are saying in here. Most monks can also be conscripted, only monks with higher degrees in Buddhist studies are exempt.
strawmanning, is an informal fallacy where one misrepresents a persons stance to make it easier to attack. It involves presenting a distorted or exaggerated version of someone's position and then attacking that misrepresentation instead of the actual argument.
You're strawmanning because you can't argue that there is are no laws like you believe/believed. You have no idea what my stance is on anything regarding immigration. You've just made a bunch of assumptions and ran with them... Pointing out you are incorrect and ill-informed does not in anyway shape or form indicate my position on immigration laws or those that come to Thailand. Nice try though, try harder next time
