At Thailand Global Visa, we assist applicants from all over the world and have identified the most frequent mistakes that lead to delays or refusals.Here are the top errors to avoid—and how to make your application as strong as possible.

Understanding the Visa Application Process

Before examining the mistakes, it is important to understand the general steps required for most visa applications. While each country has its own rules, the process typically includes:

• Reviewing visa requirements for your specific category

• Preparing the required documents

• Completing the application form accurately

• Submitting the application within the correct timeframe

• Attending an interview, if required

  
  

Mistake 1: Failing to Check Specific Requirements

Each country has unique requirements, and what applies to one visa may not apply to another. Not checking these details is one of the most common reasons for delays or refusals.

Examples:

• Schengen visas require travel insurance with minimum coverage of €30,000

• Student visas often require an official acceptance letter

  
  

Recommendation: Always consult the official embassy or consulate website for the most accurate and up-to-date requirements.

Mistake 2: Errors on the Application Form

Even a small mistake can result in a rejection. Applicants often overlook spelling, dates, or inconsistencies between documents.

Avoid:

• Misspelled personal details

• Incorrect dates

• Information that does not match supporting documents

  
  

Recommendation: Review the form several times and, if possible, have someone else verify it.

Mistake 3: Missing or Incomplete Documents

Failing to include required documents is another major source of application issues.

Commonly required documents include:

• A valid passport (often with at least six months’ validity after your return date)

• Identity photos meeting the specific size and background requirements

• Proof of financial means

• Travel itinerary or accommodation details

• 
  

Recommendation: Use a checklist to ensure nothing is forgotten before submission.

Mistake 4: Ignoring Deadlines

Visa processing times vary. Applying too late can cause unnecessary stress or missed travel dates.

Recommendation: Start the process well in advance and monitor the official processing timelines for your visa category.

Mistake 5: Not Following Submission Instructions

Embassies have specific submission rules, and failing to follow them can lead to delays.

Check:

• Whether applications must be submitted in person or online

• Required payment methods

• Document format and file size (for online submissions)

Mistake 6: Poor Interview Preparation

If the visa requires an interview, not preparing properly can weaken your chances of approval.

Recommendation:

• Review your application thoroughly

• Prepare answers to common questions about your travel purpose, employment, and financial situation

Mistake 7: Providing Misleading or False Information

Submitting incorrect or dishonest information can lead to immediate rejection and future visa complications.

Avoid:

• Altered or fake documents

• Incorrect statements regarding travel purpose or financials

Honesty is vital throughout the entire process.

Mistake 8: Not Tracking Your Application

Some applicants submit their forms and never check the status again. This can result in missed notifications or required updates.

Recommendation:Use the online tracking tools provided by embassies, or stay in contact with the consulate if updates are needed.

Mistake 9: Not Seeking Help When Needed

The visa process can be confusing, and many applicants make avoidable mistakes because they hesitate to ask for assistance.

Options:

• Professional visa consultants

• Immigration service agencies such as Thailand Global Visa

• Online communities and forums

Mistake 10: Lack of Patience

Visa processing often takes time. Rushing the process may cause errors.

Recommendation:Stay organized, double-check your documents, and allow sufficient time for processing.
