In recent years, more and more Chinese 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 Chinese 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. But for applicants of specific nationalities (especially Chinese passport holders), this error message often doesn’t mean “fields left blank” in the literal sense. Instead, it’s frequently the system’s generic response to special verification requirements for specific information.

🚨 Revealing the True Reasons: The System’s “Underlying” Checks

For Chinese passport holders, the most common “underlying” reasons for rejection are:

• “Sensitivity” of Passport Information: The system might have stricter verification mechanisms for certain specific information (e.g., Place of Birth, Place of Passport Issue). Even if you filled it in, if the format or content cannot be fully recognized or verified by the Vietnamese system, it triggers this generic error.
• Substandard Quality of Photos or Scans: Even though you uploaded them, issues like photo clarity, portrait size/proportion, glare on the passport scan, or incomplete edges can cause this. If the reviewing officer deems the quality insufficient, the system often categorizes it generically as “incomplete information.”

💡 Key Reminder: This error message is more like the system telling you: “Your information appears filled on the surface, but it’s not sufficient for me to proceed with the next stage of background checks.”

🔍 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.

🚀 Step 3: Supplementary Documents & Expedited Service (Quick Guide)! Rescuing Your Application

Once you receive a rejection notice or confirm you’ve encountered the issues above, you need to proceed with “Supplementary Documents” or “Expedited Processing” quickly to avoid travel delays.

1.Supplementary Documents Process

Supplementary Documents Process

Step	Description	Key Action
1. Find Rejection Email	Carefully read the notification email from the Vietnam Immigration Department (or the authorized agency).	Confirm exactly which documents are being requested. Do not overlook any details in the email.
2. Prepare Supporting Docs	Prepare common additional documents required for visa verification to prove your travel purpose.	• Flight booking confirmation (round-trip) • Hotel reservations (for the entire stay) • Brief travel itinerary • Invitation letter (if applying for business or family visit)
3. Submit Supplementary Docs	Follow the specific instructions provided in the notification email.	Compile the documents clearly into PDF or image files and submit them via the official website, typically using an ‘Edit’ function to modify your existing application.
4. Re-payment?	If this is your first request for supplementary documents, usually no re-payment is required.	If you are starting a completely new application, you will need to pay the fee again. Always follow the official instructions provided.

2.Expedited Service Solutions

If your departure date is very urgent (e.g., within a week), waiting for standard supplementary document processing might be too slow. Consider the following “expedited” channels:

Use a Professional Vietnam Visa Agency:

• Advantage: Agencies are very familiar with the nuances and potential requirements of the Vietnamese visa review process. They can precisely guide you in preparing documents and often use internal channels for expedited processing.
• Cost: Requires paying an additional service fee and expedite fee, making it more expensive than self-application.
• Best for: Applications already rejected with tight deadlines, or complex document situations.

• The system persistently shows “Please fill in all required information” or is stuck on “Processing.”
• Your flight departs within 48 hours, but the visa hasn’t been issued.
• The official processing time has exceeded 5 working days.
