Six steps to the Thailand eVisa submission process.
Hello Thailand!
1. Uploading the Wrong Passport Photo Format
The Mistake: Submitting selfies, cropped photos, or outdated passport-style images that don't meet Thai immigration standards.
Why It Costs You: Thailand's eVisa system automatically rejects applications with non-compliant photos, adding weeks to your processing time.
The Fix:
✅ Use a recent color photo taken within the last 6 months
✅ White background with no shadows or patterns
✅ Neutral expression, eyes open, mouth closed
✅ No glasses, hats, jewelry, or digital filters
✅ Exact dimensions: 3.5 x 4.5 cm (Thai passport size)
✅ JPEG or JPG format, under 3MB
💡 Pro Tip: If you are not tech-saavy, you may want to visit your local passport photography service to secure your photo. If you’re in the United States, FedEx Office stores are a good option.
2. Submitting Poor-Quality Passport Scans
The Mistake: Uploading blurry smartphone photos or partial scans of your passport's biographical page.
Why It Matters: Immigration officers must clearly verify your full name, passport number, expiration date, and machine-readable zone. Unclear scans trigger automatic rejections.
The Fix:
✅ Scan your passport's biographical page OR retake the photo with a better smartphone camera
✅ Use high-resolution color scanning or photo (300 DPI minimum)
✅ Ensure the entire page is visible with no cut-off edges
✅ Remove shadows, glare, and fingerprints
✅ JPEG or JPG format, under 3MB
✅ Verify your passport is valid for at least 6 months beyond your arrival date, 12+ months for multiple entries
3. Using Incompatible File Formats
The Mistake: Uploading documents in .HEIC (iPhone default), .DOCX, .WEBP, or other unsupported formats.
Why It Fails: Thailand's eVisa portal only accepts specific file types and will silently reject incompatible uploads without error messages.
The Solution:
✅ Photos: JPEG or JPG only (according to the official manual page 25 https://thaievisa.go.th/static/English-Manual.pdf)
✅ Keep all files under 3MB
✅ Convert iPhone HEIC files to JPEG/JPG before uploading
✅ Test file compatibility on the official portal first
4. Providing Incomplete Travel Information
The Mistake: Leaving blank fields for flight details, accommodation, or travel dates because plans aren't finalized.
Why It Backfires: Even with flexible travel plans, Thailand requires complete itinerary information. Missing details cause processing delays or outright rejections.
How to Handle It:
✅ Book refundable flights and hotels for application purposes (if needed)
✅ Provide your first hotel name and full address
✅ Include approximate arrival/departure dates and flight numbers
✅ For family/friend stays, provide their complete address and contact information
✅ Use booking platforms like Agoda or Booking.com with free cancellation (if needed)
📱 Quick Fix: Many travelers book flexible accommodations specifically for visa applications, then modify reservations after approval.

5. Data Inconsistencies and Typos
The Mistake: Mismatched names, incorrect passport numbers, or typos in dates of birth between your passport and application.
Why It's Critical: Any discrepancy between your official documents and visa application raises red flags with immigration authorities.
The Prevention:
✅ Double-check every field character by character
✅ Match your passport exactly—no abbreviations or nicknames
✅ Verify dates are in the correct format (DD/MM/YYYY)
✅ Have someone else review your application before submission
✅ Use copy-paste for passport numbers to avoid transcription errors
6. Last-Minute Application Timing
The Mistake: Applying just days before departure, assuming Thailand eVisa processing is always instantaneous.
Why It's Risky: While standard processing takes 3 business days, delays spike during peak seasons (November-March), Thai national holidays, and high-volume periods.
Smart Timing Strategy:
✅ Apply a minimum of 14-21 days before departure
✅ Avoid weekends and Thai public holidays for submission
✅ Don't book non-refundable flights until visa approval
✅ Consider expedited processing options if available
✅ Monitor processing times on the official website

7. Payment Processing Failures
The Mistake: Using cards or payment methods that don't support international transactions or paying through unofficial channels.
Why Payment Matters: Your application remains incomplete until successful payment. Failed transactions restart the entire process.
Payment Best Practices:
✅ Use international-enabled debit or credit cards
✅ Notify your bank about Thailand visa payment in advance, if needed
✅ Pay directly on the official Thai eVisa portal only
✅ Save payment confirmation receipts
✅ Remember: All fees are non-refundable, even for denied applications
💸 Cost Alert: Official Thailand eVisa fees range from $30-80 USD depending on your nationality and visa type.
8. Falling for Fake eVisa Websites
The Mistake: Using third-party visa services that overcharge or provide invalid documents.
Why It's Dangerous: Only the official Thai government website issues legitimate eVisas. Fake sites may steal personal information or provide worthless documents.
How to Stay Safe:
✅ Official website only: https://thaievisa.go.th
✅ Look for the secure padlock icon (🔒) in your browser
✅ Avoid sites promising "guaranteed approval" or "same-day processing"
✅ Be suspicious of prices significantly higher than official fees
✅ Check website URLs carefully for typos or suspicious domains

9. Misunderstanding Visa Validity vs. Stay Duration
The Mistake: Confusing how long your visa is valid with how long you can stay in Thailand.
Why It Confuses Travelers: Many assume a 90-day visa validity means 90 days in Thailand—leading to overstay violations.
The Reality:
✅ Visa validity: How long you have to enter Thailand (usually 90 days from approval)
✅ Duration of stay: How long you can remain in Thailand (typically 15-60 days depending on nationality)
✅ Check your specific allowance based on citizenship
✅ Overstaying results in daily fines and potential entry bans
📌 Important: Visa rules vary by nationality. Please carefully review your country-specific information for best results.
10. Missing Critical Follow-Up Communications
The Mistake: Ignoring emails from Thai consulates requesting additional documentation or clarification.
Why It Kills Applications: Unresponded requests automatically result in application denial after the deadline expires.
Email Management Tips:
✅ Check email and spam folders twice daily after applying
✅ Respond to all official requests within 48 hours
✅ Save your application reference number and confirmation emails
✅ Set up email alerts for messages from Thai immigration
✅ Keep digital copies of all submitted documents for quick resubmission
