What is the duration of my stay that I can enjoy in Singapore when my course ends?
After completing your course in Singapore, the amount of time you can stay in the country under your Singapore student visa—also known as a Student’s Pass—is usually limited. In most cases, the Immigration & Checkpoints Authority (ICA) allows international students to remain in Singapore for up to 30 days after their course officially ends. This grace period is granted to help students settle any final matters, make travel arrangements, or apply for a new type of pass if they plan to stay longer.
