In case you would like to stay in Vietnam longer than the visa validity on your passport, visa extension is really a helpful service. As long as your Vietnam visa is extended, you can continue staying in Vietnam without exiting the country and returning to apply for a new visa. It is said that the procedure of extending a Vietnam visa is very complicated and time consuming. However, it is not true at all. At the present, travelers can extend their visa for an extra 1 month or 3 month period with normal processing time is no more than 1 week.
