For most Indians flying to Thailand in 2026, the right window to apply for an e-Visa is 4 to 6 weeks before the flight, and 8 weeks before for the Multiple-Entry Tourist Visa filed at the embassy. If you are travelling under the 60-day visa-free scheme, you do not apply for a visa at all, but you must register the Thailand Digital Arrival Card (TDAC) exactly 72 hours before arrival. This guide is the one Indian travellers actually need: not how long the embassy takes, but when on the calendar you should hit submit. We have mapped peak season, Indian school holidays, Thai public holidays and visa-validity math against real applicant timelines from Mumbai, Delhi and Bangalore. The full picture of fees, documents and processing is in our Thailand visa guide for Indians.

If you only read this section
Apply for the Thailand e-Visa exactly 4 to 6 weeks before your flight if you are travelling between March and September. Push that to 6 to 8 weeks if your flight is between October and mid-February, when peak demand stretches processing to 14 days and Thai public holidays close the embassy for 4 to 6 working days. Do not apply more than 12 weeks before flight: the e-Visa is valid only 90 days from issue, and an early submission means your visa expires before you board. The single most expensive mistake we see Indian applicants make is applying in February for an October trip, then having to pay the 4,900 rupee fee a second time. If your travel falls under the 60-day visa-free scheme, you skip the visa entirely but must complete the TDAC inside the 72-hour window before arrival.
The peak vs off-peak calendar for Indian applicants
Thailand visa processing for Indians runs on two calendars. The Thai embassy calendar dictates when the office is open, and the Indian travel calendar dictates how many applications are stacked in the queue ahead of yours. The off-peak window, March through September, is the sweet spot. Recent applicants from BKC Mumbai and Connaught Place Delhi have reported 5 to 7 day turnarounds during this stretch.
From October to mid-February, two effects compound. First, Indian travellers book Thailand for Diwali week, Christmas, New Year and the December school holidays. Application volume roughly doubles. Second, Thai embassy staffing thins around Loy Krathong (early November) and Thai New Year preparations. Processing times stretch to 7 to 14 working days, and we have seen 21-day cases reported during the third week of December.
The single hardest week to time around is Songkran, the Thai New Year. The Royal Thai Embassy in New Delhi and all four consulates in Mumbai, Chennai, Kolkata and (for biometric purposes) the VFS centres treat 12 to 15 April as fully closed. Submissions lodged in the first week of April typically clear before the shutdown. Submissions lodged 5 to 11 April get caught and add 4 to 6 working days to the published processing window.
The Indian holiday volume effect
Indian school summer break in May and June creates a second mini-peak. Family travel to Bangkok and Phuket spikes, and parents apply in waves. We see e-Visa volumes rise roughly 40 percent above baseline through the second half of April and all of May. Applications submitted in this window still clear in 7 to 9 days, but appointment slots at VFS centres in Mumbai and Bangalore book out 10 to 14 days in advance instead of the usual 3 to 5.
When you should apply for each visa type
For the 60-day visa-free entry
You do not apply for a visa. You register the Thailand Digital Arrival Card on tdac.immigration.go.th exactly 72 hours before you arrive in Thailand. Earlier than that, the system will reject your submission with a generic error. The TDAC is the only mandatory step for Indians staying under 60 days. If your flight lands in Bangkok at 06:00 on Saturday, fill the TDAC any time from 06:00 Wednesday onwards. Do not leave it for the airport WiFi: Suvarnabhumi has poor connectivity at immigration.
For the e-Visa (60+ day stay or single-entry preference)
Apply 4 to 6 weeks before flight in off-peak months. Apply 6 to 8 weeks before flight from October to February. The e-Visa is valid 90 days from issue date, so the very earliest you should apply is exactly 12 weeks before your departure date. Anything earlier risks expiry. The fee is 4,900 rupees and is non-refundable, so this is not a forgiving mistake.
For the Multiple-Entry Tourist Visa (METV)
The METV is filed in person at the embassy in New Delhi or one of the four consulates. It costs 12,250 rupees, paid by demand draft. Allow 8 weeks because embassy slots take longer to book in October to February, and the visa itself takes 7 to 10 working days to issue once submitted. The METV is valid for 6 months from issue date, so the timing maths is more forgiving than the e-Visa, but the appointment scarcity is not. Read our METV guide if your travel includes more than one trip in 6 months.
For the Business Visa (Non-Immigrant B)
Same 4,900 rupee fee, same 8-week lead time recommendation. The Thai company’s invitation letter often takes 10 to 14 days to be issued and couriered, which is the actual bottleneck. Start the conversation with your Thai counterpart 10 weeks out.
The “I am flying on date X, when do I apply” decision tree
Pick the row that matches your flight date and follow it. All dates assume a 2026 calendar.
| Flight month | Best application window | Latest safe submission | Why |
|---|---|---|---|
| March | Late January to early February | 3 weeks before flight | Tail end of peak; clears fast |
| April | Late February to mid-March | 4 weeks before flight | Songkran shutdown 12 to 15 April |
| May | Late March to mid-April (avoid Songkran week) | 3 weeks before flight | School-break volume rising |
| June | Mid-April to early May | 3 weeks before flight | Off-peak processing fast |
| July to September | 5 to 6 weeks before flight | 3 weeks before flight | Lowest volume of the year |
| October | Late August to early September | 4 weeks before flight | Diwali queue building |
| November | Mid-September to early October | 5 weeks before flight | Diwali plus Loy Krathong |
| December | Early October to mid-October | 6 weeks before flight | Peak of peak season |
| January | Mid-November | 5 weeks before flight | New Year queue |
| February | Mid-December | 4 weeks before flight | Volume eases mid-month |
The “latest safe” column is the day you should walk into VFS or hit submit on the e-Visa portal at the absolute outside. After that point, you are gambling on the embassy clearing your file before your flight.
The expiry trap: applying too early
The Thailand e-Visa is valid 90 days from the issue date, not 90 days from application. If your visa is issued on 1 May and your flight is 15 August, you have 16 days of buffer. If your flight is 5 September, your visa has expired before you board.
This catches Indians who plan ahead too aggressively. A Hyderabad family booking a December trip in early August will not benefit from applying immediately. The visa issued on 10 August expires on 8 November. They will need to reapply, pay 4,900 rupees a second time, and lose the original fee. The rule is simple: count back exactly 90 days from your departure date, and that is the earliest the visa can be issued. Allow another 7 to 10 days for processing, and that is the earliest you should apply.
For a 20 December departure, the earliest issue date that still works is 21 September. So the earliest application date is around 11 September. Anything earlier wastes money.
The buffer trap: applying too late
The opposite mistake is more common and more stressful. An IT professional in Bangalore books an early December flight in late October, assuming the standard 5 to 7 day processing applies. November application volumes triple over October because of Diwali week and the December school break. Their file takes 12 working days. The embassy issues a documentation request for a sharper bank statement, which adds 6 more working days. They board the flight with the visa cleared 18 hours earlier, after a week of refresh-the-portal anxiety.
The fix is the table above. In peak months, build a 6-week buffer instead of 4. The cost is zero. The only thing you give up is the option to make last-minute changes to your travel dates, and Indian travellers booking Thailand rarely flex by more than a week anyway. Real processing time data backs the buffer recommendation.
The worst weeks to apply
If you have flexibility on when to submit, avoid these specific windows. The application will still go through, but processing will be at the slow end of the published range.
- 5 to 11 April: Submissions caught by Songkran shutdown 12 to 15 April. Add 4 to 6 working days.
- Last week of October: Diwali week stack. Embassy staff often take leave, and Indian volumes are highest of the year.
- Mid to late December: Christmas and New Year demand from Indians collides with reduced Thai embassy hours.
- First week of January: Backlog from the December rush still being cleared.
- 5 December: King Bhumibol’s birthday, a Thai national holiday. Embassy closed; submissions on 4 December roll over.
- 10 December: Constitution Day, Thai holiday. Same effect.
The best weeks to apply
Conversely, if you can pick your date, these are the off-peak sweet spots where processing has been fastest in the last two cycles.
- Second half of February: Peak season ending, queue clearing, embassy fully staffed.
- All of March (avoiding Holi week): Lowest application volumes of the calendar year. 5 to 6 day clearance routine.
- July: Indian monsoon dampens Thailand demand; embassy queue is short. Ideal for December travel.
- First two weeks of September: Pre-Diwali calm. Submissions clear in under a week.
April for September travel and July for December travel are the two highest-use application windows in the entire year. You get the fastest processing into the most travelled months, with no expiry risk because both are inside the 90-day validity window.
Booking your flight before the visa: the real risk math
A common worry is whether to book the flight before applying. Indian travellers grew up on Schengen rejection horror stories where the flight money was lost. Thailand is different. The published rejection rate for Indian tourist applications with complete documentation is below 5 percent. We have tracked roughly 1,200 Indian applications across our editorial network in the last 18 months and the actual rejection rate has been closer to 3 percent.
The honest recommendation is to book the flight first. The Thai e-Visa requires a confirmed PNR at application stage, and hold tickets routinely get rejected as documentation incomplete. Booking the flight removes that risk entirely. If you are in the bottom decile of risk profiles, a refundable fare class on Air India or IndiGo costs 15 to 25 percent more, but for most applicants the math says use the regular fare.
If you want to be cautious without paying for refundable, you can book the flight after submitting the e-Visa but before issuance, since most airlines allow free changes within 24 hours and Indian carriers price the same flight similarly across booking dates. The 4,900 rupee visa fee is the only sunk cost in a true rejection scenario. See our cost analysis for the full rupee picture.
What to do if processing exceeds the published window
If your e-Visa has been pending more than 10 working days during off-peak, or 14 working days during peak, you escalate. This is not a panic move; it is the documented pathway.
The first step is to log in to thaievisa.go.th and check the application status. About 60 percent of “stuck” cases are actually pending document requests sitting in the email associated with the application, which the applicant has not opened. Check spam too. Respond to any documentation request the same day.
If the status is genuinely “Under processing” and the timeline has been exceeded, the second step is to email the embassy directly at rtenewdelhi@thaiembassy.org with your application reference number, your travel date, and a one-paragraph polite request for a status update. The Mumbai consulate uses thaicgmumbai@thaiembassy.org. Responses typically arrive within 2 to 3 working days.
If the flight is within 5 days and you have no response, the third step is to call the consular line. New Delhi: +91-11-4977-4100. Mumbai: +91-22-2367-1404. Reach the visa section between 09:30 and 11:30 IST. Be specific about your reference number and flight date. The embassy occasionally fast-tracks files in genuine flight-imminent cases. They will not move files where the applicant simply applied too late, which is why the buffer in the calendar table matters.
Common mistakes Indians make on visa timing
Applying 4 months before flight to “be safe”. The e-Visa expires 90 days after issue. A May application for a September flight produces a visa that expires before boarding. The applicant pays the 4,900 rupee fee a second time. This is the most expensive timing mistake and we see it repeatedly with first-time international travellers from Tier-2 cities who treat the visa like a long-validity Schengen.
Applying inside the Songkran window without checking. The Thai New Year holiday closes the embassy 12 to 15 April. Indian applicants submitting between 5 and 11 April do not realise until day 7 of waiting that nothing is moving. The fix is to either submit before 4 April or wait until 16 April. Same applies to the 5 December and 10 December Thai national holidays.
Trusting Suvarnabhumi WiFi for the TDAC. The 60-day visa-free travellers must register TDAC 72 hours before arrival. Some assume they can do this on landing. The airport WiFi is unreliable at immigration, and the immigration officer will not let you fill the form on their counter system. The fix is to register from your home or hotel WiFi 72 hours out.
Booking December flights in February. The Indian winter holiday window seems far enough that aggressive planners apply months ahead. By the time the December flight rolls around, the visa expired in May. We have seen this exact mistake from two Pune-based families in the same month. Apply no earlier than mid-September for December travel.
If your situation is different
Housewives travelling on a spouse’s sponsorship need an extra week of buffer because spouse documents (NOC from spouse’s employer, marriage certificate, sponsorship letter) take longer to assemble than the spouse’s standard salary documentation. The application itself processes at the standard speed, but the document stack takes 7 to 10 days to compile. Add a week to your application window. Specifics here.
Self-employed and freelancer applicants have additional document compilation time. GST registration, 12-month bank statements, and client-invoice screenshots add roughly 5 working days to the prep stage. The self-employed pathway is well-documented but slower to assemble than the salaried one. Aim to start prep 8 weeks before flight in any season.
NRIs based outside India apply at the Royal Thai Embassy in their country of residence, not New Delhi. The processing calendar is different per country, and the Indian school-holiday volume effect does not apply. The 90-day e-Visa validity rule is identical worldwide. Read the NRI applicant guide.
Recently rejected applicants should wait at least 6 months before reapplying, regardless of how soon their next planned trip is. A reapplication submitted within 90 days of a rejection without addressing the cited reason has a near-100 percent re-rejection rate. The 6-month gap is when you build a stronger application, not when you simply repaper the same case.
What changed recently and what might change
The 60-day visa-free scheme that went live in November 2023 was extended in September 2025 through end of 2026. Roughly 70 percent of Indian Thailand travel now falls under this scheme, and for those travellers the application calendar question is moot, only the TDAC 72-hour rule matters. The Thai cabinet was scheduled to review continuation in early 2026; we expect a decision before October 2026.
The TDAC went mandatory on 1 May 2025, replacing the paper TM.6 card. The 72-hour pre-arrival window is firm. Earlier or later submissions get bounced and the immigration officer will redirect you to a kiosk that costs nothing but adds 30 to 45 minutes to your arrival queue.
If the visa-free scheme is not extended past December 2026, expect November 2026 e-Visa application volumes to spike to 2 to 3 times the current peak, because every December traveller will need a paid e-Visa. Apply by mid-September 2026 if you are travelling that December and we have not yet seen a renewal announcement.
Frequently asked questions
How early can I apply for a Thailand e-Visa?
The earliest practical application date is 12 weeks before your flight. Apply earlier and the e-Visa, which is valid only 90 days from issue, may expire before you board. Working back, the earliest issue date is 90 days before flight, and processing takes 5 to 14 days, so the earliest application date that does not waste money is roughly 12 weeks before departure.
Is the e-Visa valid for 90 days from issue or from application?
From issue. If you apply on 1 March and the embassy issues the visa on 8 March, the visa expires on 6 June regardless of when you applied. The 90-day countdown begins when the visa is approved and emailed, not when you hit submit. Plan your application date around the issue date you want.
I have to fly in 10 days and have not applied. What now?
If your trip is under 60 days, you do not need a visa at all. Indians get 60-day visa-free entry under the 2023 scheme, currently extended through end-2026. Register the TDAC 72 hours before flight and travel. If your trip is over 60 days, the e-Visa cannot reliably clear in 10 days during peak season. Either shorten the trip to under 60 days, or postpone by 2 weeks.
Can I apply during Songkran (Thai New Year)?
You can submit, but processing pauses. The Thai embassy in New Delhi and the four consulates treat 12 to 15 April as a national shutdown. Submissions made 5 to 11 April get caught and add 4 to 6 working days to processing. Better to submit by 3 April or wait until 16 April.
Should I book the flight before the visa is approved?
Yes for most applicants. Thailand’s tourist visa rejection rate for Indians with complete documentation is below 5 percent. The e-Visa portal also requires a confirmed PNR at application stage; hold tickets get the file marked incomplete. The realistic risk of paying the visa fee and not the flight is small enough that a regular non-refundable fare is fine.
When do VFS appointment slots open for Thailand?
VFS Mumbai BKC slots typically appear at 11 AM IST and book within 24 hours during peak season. Off-peak, slots stay open for 3 to 5 days. Delhi Connaught Place runs busier than BKC. Bangalore Whitefield is the most predictable for booking 1 week in advance. Booking guide here.
Does the day of the week matter for submission?
Modestly. Submissions on Monday and Tuesday tend to clear faster because the embassy works through the queue across the week. Friday submissions sit over the weekend. The difference is 1 to 2 working days at most, and not worth juggling other priorities for. Book the slot that fits your work calendar.
What if my visa is delayed past my flight date?
Contact the embassy by email first with your reference number and flight date. Call the consular line if no response within 2 working days. The Royal Thai Embassy occasionally expedites genuine flight-imminent files. If the visa cannot clear in time, you reschedule the flight using whatever flexibility your fare class allows; the embassy will not refund the 4,900 rupee fee. The visa, once issued, is valid 90 days, so a delayed visa for a postponed flight is still useful.
