The C18 Work Trial Visa is a unique and innovative permit that allows foreign professionals to visit Indonesia for a probationary period or a skills assessment with a potential employer. This visa addresses the need for both companies and candidates to ensure a "good fit" before committing to a long-term KITAS (Work Permit).

​

During the 90-day period granted by the C18, the individual can observe company operations, demonstrate their expertise, and participate in training sessions. It is a transparent and legal way to handle the pre-employment phase, which was previously a gray area in immigration law.

​

However, as of recent 2026 updates, the C18 is a single-entry visa and is strictly non-extendable. Once the 90 days are up, the candidate must either transition to a full Work KITAS or leave the country. This visa is a testament to Indonesia's modern approach to international recruitment, providing a professional pathway for global talent to prove their value to the Indonesian workforce while ensuring that both parties are satisfied before entering a formal contract.
