First thing you do is you wait till your DTV is approved, then decide on when you want to go to Thailand. Why would you ask the embassy something about an error in your flight date? It has nothing to do with your DTV submission

you go to IT LAKSI square to extend a visa exempt stamp.

Do you have an actual visa that you bought before coming here, or did you get a free 60 day visa exempt entry stamp when you entered? Depending on which is true you would go to a certain office to get your extension. You can't shop around you go to the office with jurisdiction over the area where you filed your TM30.

You move, you get the new landlord to file a TM30, you go to the local office and file a TM27 notification of address change. If for instance you bought a 90-day non-o at the local immigration office in Phuket then you must do your first extension there.

When getting the 2nd year entry, you must buy a single or multiple re-entry permit to keep your permission to stay stamp alive if you plan on leaving the country. The multiple entry benefit of the original visa is not carried over once the visa validity date has expired.

You can fill in as much of the online application form as possible before you get there, it will save your application up to 14 days before automatically deleting it, and then once you get to Vietnam you can double check your data, upload your proof of location info, submit and pay. With the upcoming Songkran holiday you might want to delay your trip a week.

@Rafael ********

your application was cancelled, not rejected. A cancellation usually means improperly entered passport data.

non IMM O visa 90 days, then transfer 800k baht to Thailand, let it season for 2 months and apply for year extension 1900 baht. After extension is granted then buy a multiple re-enter permit 3800 baht
