COE approval means the Immigration Services Agency of Japan has officially confirmed that:
Once approved, the COE is issued. This is not the visa, but it is the most important document to get the student visa.
Note: The documentation stage is critical — missing or incorrect documents can delay COE approval. So double-check translations, signatures, and financial proofs.
✔️ COE approval = you are eligible to stay in Japan ✔️ COE does not allow entry by itself (visa required) ✔️ COE validity: 3 months (you must apply for visa within this time)
