Why applications on this route get refused
No Ministry of Labour approval letter
Applying without the WP3 approval letter from the Ministry of Labour, which only your employer can obtain, doesn't meet the visa's core requirement.
How to avoid it: Confirm with your employer that Form WP3 has been submitted and approved before you apply for the visa.
Insufficient evidence of finance
Not showing the stated 20,000 Baht (individual) or 40,000 Baht (family) can lead to refusal.
How to avoid it: Prepare bank evidence clearly showing the required amount before applying.
Incomplete employer company documents
Missing business registration, shareholder list, or financial/tax documents from the hiring company is a common reason applications are held up.
How to avoid it: Check with your employer's HR or legal team that all corporate documents are gathered before you submit your application.
