DTV (e-Visa) can be applied for online, but the document upload stage is where many applicants run into trouble. Here's what to check before submitting so you don't get stuck after gathering all your documents.
What you'll learn: Common issues that arise when uploading documents to the e-Visa system, and what to prepare in advance to avoid them.
How Document Submission Works
DTV (e-Visa) applications are submitted through Thailand's Ministry of Foreign Affairs e-Visa portal. The standard flow involves completing the application form and uploading documents online.
That said, some embassies may request supplementary documents by email. Always follow the official guidance from your application embassy.
Common Upload Issues
File Format Problems
The e-Visa system generally accepts PDF, JPEG, and PNG. Attempting to upload unsupported formats such as Word or Excel files typically results in an error.
Solution: Convert all documents to PDF or the specified format before submitting.
File Size Limits
The e-Visa system may impose a maximum file size per upload. High-resolution scans of documents can exceed this limit.
Solution: Use a compression tool to reduce file size before submitting. Avoid compressing to the point where text becomes unreadable — compress only as much as needed while keeping the content clearly legible.
Merging Multiple Documents into One File
Some application screens only allow one file per field. If you cannot upload multiple files separately (e.g., three invoices), they must be merged into a single PDF.
Solution: Use Adobe Acrobat or an online PDF merge tool to combine multiple pages into one file.
Passport Photo Page Scan Quality
The passport photo page must be scanned clearly enough for text, the photo, and the MRZ (machine-readable zone) to be legible. Dark, tilted, or blurry scans are a common cause of rejection.
Solution: Scan flat in a well-lit area and confirm that all four corners are fully visible.
Photo Size and Format Requirements
The applicant photo has specific requirements for pixel dimensions, background color, and orientation. Smartphone photos may not meet these requirements.
Solution: Use a photo taken at a photo studio or photo booth, or resize and edit your photo according to the system's requirements.
