10. Frequently Asked Questions {#section-10}
Q. Do I need health insurance if I'm on a short-term work visa (C-4) or tourist visa? A. No. Foreigners planning to stay less than 6 months are not required to enroll. However, once you switch to a long-term work visa (E-7, E-9, etc.), enrollment becomes mandatory immediately.
Q. Do my spouse and children each need to pay separate premiums? A. If your spouse and children qualify as dependents under NHI, they can be added to your plan at no additional premium. Dependent eligibility is based on income and property thresholds.
Q. I already have health insurance from my home country. Do I still need Korean NHI? A. Nationals of countries with bilateral social security agreements with Korea (such as Germany or the US) may be exempt upon submitting proof of home-country coverage. Check with NHIS for your specific country.
Q. What happens if I fall behind on premium payments? A. Overdue premiums can result in demand notices, possible wage or asset garnishment, and negative impact on visa reviews. If you fall behind, pay as soon as possible or apply for an installment plan.
Q. How much will hospital visits cost without health insurance? A. Without NHI, you pay 100% of medical costs, which can be 3–5 times higher than insured rates. Enrolling before seeking medical care is strongly recommended.
