No, travel insurance is not mandatory for a Singapore Visit Visa. Although travel insurance is not a requirement for a Singapore Visit Visa, it is a good idea to have it. It covers things like medical issues, cancelled trips, and accidents, which can save you money if something goes wrong while you are there. Some visa services or airlines might want to see proof of insurance before they book your trip. It is really important if you are traveling with children, older people, or going for medical care. A policy that covers at least SGD 30,000 for medical costs is usually enough.
