Complete Guide for Hong Kong Applicants to Vietnam Visa | Encountered the “Please fill in all required information” Error? This Article Teaches You How to Resubmit Documents and Expedite Your Application

When you’re excitedly preparing to submit your Vietnam E-visa application, a confusing warning suddenly pops up: “Please fill in all required information.” Don’t panic! This message is not a rejection notice; it’s the system telling you that there is information in your application form or uploaded documents that does not comply with the strict standards of the Vietnamese authorities.

For Hong Kong applicants, understanding the details of the Vietnam E-visa system is crucial. This article will provide an in-depth analysis of the common causes of this error, offer the most precise correction guide and resubmission process, and outline emergency expediting options to ensure you can successfully obtain your visa and begin your journey to Vietnam.

🔍 Part 1: “Please fill in all required information”: Error Detection and Correction Checklist

When the system rejects your submission or asks you to go back and make corrections, please act like a professional detective and check against the following two common error types one by one.

A. 📝 Basic Personal Information Entry and Format Errors

Error Item	Common Mistakes	💡 High-Score Correction Guide
Name Spelling	Surname (Last Name) and Given Name (First Name) fields are swapped, filled in Chinese, or contain non-English letters.	💯 Use ALL UPPERCASE ENGLISH letters. Surname and Given Name must be entered in separate fields and exactly match the English spelling on your passport.
Date Format	Using a format not specified by the Vietnamese system (e.g., YYYY/MM/DD or MM-DD-YYYY).	💯 Consistently use the DD/MM/YYYY format (Day/Month/Year).
Address	Using Chinese to fill in the residential address or Vietnamese accommodation address.	💯 Use English throughout.
Passport Validity	Passport has less than three months of validity remaining from the intended date of entry.	💯 Passport must have at least 3 months of validity remaining. If insufficient, renew your passport immediately first.
Purpose of Entry	Selecting an option other than “Tourist”.	💯 For tourist visas, uniformly select Tourist to ensure a smooth approval process.

B. 📸 Uploaded Document Specifications and Clarity Issues (The Most Common Reason for Rejection for Hong Kong Applicants)

The Vietnam E-visa system has extremely strict requirements for uploaded electronic files. Unclear documents, glare, or incorrect formats are the primary reasons causing this system error message.

1. Passport Data Page Scan

Completeness: Must be a color scan or high-resolution photo. All four corners of the passport page must be fully visible, with no cropping.
Clarity: Avoid glare or shadows. The machine-readable zone (ICAO code, the long string with <<< symbols) at the bottom of the page must be extremely clear and legible.
Format & Size: Usually requires JPG/JPEG format. Recommended file size is under 200KB.

2. Personal Portrait Photo Electronic File

Background & Face: Must be a recent color photo with a white background. Face should be centered, with facial features (eyebrows, ears) clearly visible.
Important Notes: No colored glasses, no smiling showing teeth. No hats (except for religious reasons).
Format & Size: Usually requires JPG/JPEG format. Recommended file size is under 50KB.

💡 Important Reminder: Many applicants use mobile phone photos without compression or cropping, resulting in files that are too large or have incorrect proportions. Be sure to use professional online tools or apps to adjust the file specifications.

🔄 Part 2: Standard Procedure for Vietnam E-visa Resubmission (Correction)

If you have successfully submitted your application and paid the fee, and subsequently receive an official email notification requesting you to “provide additional documents” or “correct information,” please follow these steps to make the correction:

Read the Official Notification Carefully: Thoroughly read the official email from the Vietnam Immigration Department to confirm the specific file names or data fields they require you to correct or supplement.
Access the Inquiry/Modification System:
- Go to the inquiry page of the official Vietnam E-visa website.
- Enter the Registration Code you received during application, your email address, date of birth, and the security captcha.
Re-upload and Modify: Access your personal application page and make precise corrections to the items flagged for revision, or re-upload files that meet the specifications mentioned above with higher clarity.
Resubmit the Application: Double-check that all information is correct, then resubmit.

⚠️ Please Note: Any “resubmission” or “modification” action will cause your application to be treated as a new case! The official processing time (typically 3-5 working days) will start over. If you are short on time, be sure to consider the expedited service mentioned in the next section.

🚀 Part 3: Emergency Lifesaver for Hong Kong Applicants: Vietnam E-visa Expedited Processing

Faced with multiple failed resubmissions, severely overdue processing times, or an imminent flight departure, seeking professional “Urgent Processing” or “Expedited” services is the best solution to ensure you can depart on time.

The system persistently shows “Please fill in all required information” or remains stuck on “Processing” for a long time.
Your flight is within 48 hours, but the visa has not been issued.
The official processing time has exceeded 5 working days.
You have had to resubmit or correct your data two or more times.
