please provide the list of requirements for the DTV extension from your local immigration office. What? You can’t? They won’t give you list? Why not, they do for every other type of visa? Oh they say “sorry Mister, no have”. And that is the standard answer for every reported request. Unless of course you can link to the list of requirements.
For re-entries currently nothing additional is required. For in country extensions nobody knows the cost or requirements as Immigration is silent on the subject. Despite repeated requests Immigration have not published any details.
An exit ticket is part of the requirements for a visa exempt entry. If you already hold a visa you already have satisfied entry requirements. Therefore with a visa you do not need an exit ticket.
Not a problem, just show your Tax Clearance Certificate issued by the Director General of the TRD which indicates taxes are paid or you have provided securities to cover taxes owed which you applied for 15 days before leaving Thailand…..
