The Single Entry Business Visa is intended for foreign nationals who want to engage in business activities such as meetings, negotiations, or conferences in Indonesia. The visa is valid for 60 days and can be extended up to two times, with each extension granting an additional 60 days. This allows you to stay in Indonesia for a total of 180 days. However, once you leave Indonesia, the visa will become invalid, and you will need to apply for a new one if you wish to re-enter.
