In recent years, more and more American travelers are choosing Vietnam for tourism or business, and applying for the Vietnam E-visa is the preferred option for most. However, online forums frequently mention American passport holders encountering a confusing error message – “Please fill in all required information” – after uploading documents in the system, leading to their visa application being rejected or stuck.
Clearly all fields were filled, so why does this error appear? What is the real reason hidden behind this? This article will provide an in-depth analysis and offer the most practical guide to supplementary documents and expedited services, ensuring your Vietnam visa application goes smoothly!
🛑 Step 1: Misinterpreting the Error! The Real Reasons Behind “Please fill in all required information”
When you see “Please fill in all required information,” your first instinct is likely to go back and check if any fields were missed.

🔍 Step 2: Self-Help Checklist! Precise Verification Before Potential Rejection
Checklist for Application Review
| Checklist Item | Potential Link to Error Message | Solution |
| Passport Scan Page | Missing corners, glare, blurry. | Must be a complete, clear, glare-free scan of the passport data page. Use a professional scanner rather than a phone photo. |
| Passport Photo (Portrait) | Subject too small, facial shadows, cluttered background. | Strictly adhere to international standards: no borders, full face visible, no glasses or hats. |
| Place of Birth & Place of Issue | Non-standard formatting or mismatch with passport. | Must exactly match the English spelling on your passport, paying close attention even to abbreviations. |
| Entry Port & Dates | Discrepancy between selected port and actual travel plans. | Double-check that the selected airport or land border is an accepted entry point for the Vietnam E-visa. |
