Vietnam is a growing destination for foreign teachers thanks to its vibrant culture, affordable living costs, and strong demand for English education. However, many teachers face unexpected delays before they can officially start working. The main reason? Paperwork mistakes. Even small errors in your documents can lead to weeks of waiting, additional costs, or even visa denial. This guide highlights the most common mistakes and how to avoid them.

Your passport is the first thing immigration checks.
A sponsorship letter from your employer is required for work visa or TRC applications.
Vietnamese immigration requires specific forms (NA2, NA5, NA6, NA8, etc.).
Every foreigner in Vietnam must have a temporary residence registration from the local police.
Your employer must provide additional documents such as the business license, tax code certificate, and employment agreement / work contract.
Choosing the wrong visa (Tourist, Business, or Working Visa) can cause delays in converting to the correct status.
Paperwork mistakes are one of the biggest reasons foreign teachers face delays in Vietnam. From expired passports to incomplete sponsorship documents, even minor errors can hold back your teaching career. By double-checking requirements, working closely with your employer, and staying organized, you’ll avoid unnecessary stress and start teaching on time.
