Overview
Join National Health Insurance can vary by municipality and residence status. Always confirm current requirements with your municipality, Immigration Services Agency, or relevant authority. Deadlines matter for city office procedures. Some address or moving procedures may have deadlines such as 14 days, so confirm on your municipality's official page.
Do this first
- Before visiting, check appointment needs, counter hours, interpreter support, and fee payment method
- If document names are unclear, explain your purpose and ask which documents are needed
- Check your municipality's official page
- Write down required documents and deadlines
- Ask the counter about unclear points
What you need
- Residence card
- Passport
- ID document
- Proof of address
- Fee
Steps
- If you lose employer health insurance or move, ask your municipality whether NHI procedures are needed
- Check eligibility on the municipal or official page
- Confirm documents, fees, and counter hours
- Apply at the counter or online if available
- Save receipt, reference number, and next deadline
- After submission, confirm receipt, reference number, next counter, and next deadline before leaving
- If address or name spelling differs, ask early because it can affect bank or school procedures
Cautions
- Municipal rules differ
- For residence status and deadlines, confirm with the Immigration Services Agency
- Proxy applications may need extra documents
- For residence status, period, or work permission decisions, Immigration Services Agency guidance may be needed rather than only municipality guidance
- Steps may differ by area or timing. For important decisions, confirm with official sources and local staff.
