With regards to the Jakarta embassy does one just walk in there for a visa appointment? No need to book in advance?
And can a UK Passport holder make the DTV application there?
Same questions for Vientiane and Yangon.
TLDR : Answer Summary
For the Jakarta embassy, no appointment is necessary, and you can simply walk in between 9 AM and 11:30 AM from Monday to Thursday. In contrast, both the Vientiane and Yangon embassies require appointments to be booked online in advance. A UK passport holder can apply for the DTV visa at any of these consulates, as long as they can show they are legally in the country.
