Iโll be in Thailand for up to 30 days (by air) then move onto Vietnam/Cambodia. Iโll then be back in Thailand (by land) and will likely need up to 60 days for this entry. Can I apply for the 60 day tourist visa before arrival and only use it for my second entry, or will this visa be applied to my first entry only (Iโm not sure if the visa requires a date of arrival). UK passport.
TLDR : Answer Summary
The user is inquiring whether they can apply for a 60-day tourist visa for Thailand in advance of their travels, intending to use it only for their second entry after visiting Vietnam and Cambodia. Comments indicate that they cannot apply online for this visa in the UK before their first entry, as it must be used upon entry. Instead, they can enter Thailand on a 30-day visa exemption and then apply for a 30-day extension at an immigration office. Alternatively, they can apply for the 60-day visa at a Thai consulate while in Vietnam before their second entry.
