NRIs (Non-Resident Indians) studying abroad can purchase health insurance to cover unexpected medical expenses. Here are some general considerations for health insurance for NRI students:

1. Coverage: Health insurance policies for NRI students generally cover medical expenses related to accidents, illnesses, hospitalization, surgery, and emergency medical evacuation.
2. Premiums: Premiums for health insurance policies can vary based on the coverage amount, duration of the policy, and the student’s age and medical history.
3. Duration: Health insurance policies for NRI students can typically be purchased for a duration of 6 months to 4 years, depending on the policy provider.
4. Network: Some health insurance providers may have a network of healthcare providers that the student can access in case of medical emergencies.
5. Pre-existing Conditions: Some health insurance policies may not cover pre-existing medical conditions or may require additional premiums to cover them.

It is important for NRI students to research and compare the different health insurance policies available to them, and to choose a policy that provides adequate coverage at an affordable cost. NRI students should also familiarize themselves with the policy terms and conditions and keep a copy of their health insurance policy with them at all times.
