I will fill out my application form for a single entry tourist visa to Thailand for 60days I intend to travel the end of January, how soon should I submit this bearing in mind all government departments will be down over the Christmas period, and I will need to book my airfare prior to submitting paperwork as the application form asks for flight details.
Thankyou for your advice .
TLDR : Answer Summary
You can apply for a single entry tourist visa to Thailand up to 90 days before your intended arrival date. However, due to the Christmas holiday period, it's advisable to submit your application well in advance, as government offices may be closed. Additionally, it's recommended to confirm your flight bookings only after considering potential delays in visa processing. For Australians, direct online pre-approval through the consulate can be an option without needing flight proof. Some users also mention that UK applicants might have restrictions on submitting the application until 8 weeks before travel.
