Why do many prefer DTV before applying for an E-Visa in Jakarta?

My,experience is walk in is better.

Nope. Evisa has an advantage of extra chances. If your documents are missing, they will email you and ask more additional docs. Walkin applications don't have that advantage

I’ve heard that the Evisa takes longer. Also, they may request more documents. Furthermore, several people have reported that their money is NOT taken if rejected in person, they are simply told to fix the problem/bring more documents so then they only pay the fee once instead of twice. Combine these two issues and it’s really frustrating. Imagine waiting a week just to have your application rejected due to a small mistake, and then needing to wait another week and pay another fee to get approved.

People here would rather be living in or visiting Thailand, so it makes sense to bite the bullet now and get it ASAP so that you get it in reasonable time with one payment. So you see many people here cancelling their education and other visas for example because this visa will sort them. My education visa was to expire in December, but I figured better apply sooner in October instead of optimizing for 2 more months.

Finally, because this is a new visa it seems like a good idea to get it early while you can. In fact it’s a great visa, so many people might apply, so it’s better to apply early to guarantee getting it before they add more requirements like higher income or make it more of a hassle to get. Things can change, but I expect that if it did the current visas issued would be honored or the visa holders allowed to apply for another visa cost free.

In short things could change and many people want to be in Thailand so people are applying quickly to get it while it’s going good and fast.
