Indeed, especially if applying using the e-visa portal, processing times are unpredictable.
If applying in person, it's more predictable but you should still allow extra time in case you need to go back and submit more documents, which will cause processing to be delayed until such time as all documents are satisfactory. In most cases, this is just one extra business day, but do prepare to stay a couple of days extra.
If flying in to a walk-in consulate, I'd allow 5 days if the standard processing time is 3 days (meaning submit on Monday, receive your visa on Wednesday afternoon).
If it's an e-visa consulate, allow up to 2 weeks.
it's less stressful if you travel by land, without a fixed outbound ticket. From Thailand, you really don't need to fly to Cambodia or even Vietnam. Saves you a lot of headaches having to purchase new tickets in case your originally purchased fare is non-changeable and non-refundable (except for airline taxes).
Flemming Rønnow You have to do it via post or in person after every re-entry so the online thing isn't useful for DTV holders as it can only be used once before you're required to leave the country. If you get an in country extension, then you'd do a 90 day report in person (since you'd be coming in for the extension anyway) and then you might be able to do 1 online 90 day report before being required to leave the country.
Too much hassle given how limited the system is. Easier to just do a mail in report for the first 90 days, in person for the second and mail in for the 3rd one. There won't be a 4th one as you have to leave the country by then anyway.
Yes, that's what I thought. Someone claimed he could apply for a secured credit card without a work permit (he's on a retirement visa) but I doubted his story.
It's not in their computer system, that's why. It's because they're overworked, lazy or assume foreigners are coming in without a visa. Nothing to do with it being a DTV. I've been stamped in, incorrectly on visa exempt on at least 2 occasions while holding a non-O multiple entry visa just in the past 18 months alone and that was before I got the DTV.
LOL, considering it's Thai consular officials who decide whether Chinese citizens who apply in China get one or not. Nothing to do with the Chinese government.
