The KITAS (Kartu Izin Tinggal Terbatas) is an Indonesian Temporary Stay Permit, allowing foreign nationals to live and work in Indonesia for up to one year, with the possibility of renewal. It is commonly issued to expatriates for work, investment, or family reasons. The KITAS can be obtained through employment with a local company, investment in a business, or marriage to an Indonesian citizen. Applicants need to provide relevant documents, including a valid passport, proof of employment or marriage, and financial stability.
