Immigration Services Agency

Japan's formal immigration authority — where residence status extensions, changes and permits are actually filed. About the Immigration Services Agency: The Immigration Services Agency (ISA) is Japan's official body for entry, residence status and related applications. Where FRESC offers consultation, the ISA is where the formal paperwork for status extensions, changes and permits is actually submitted and processed. Key Features: Residence Status Applications: Handles extensions and changes to the residence status foreign nationals hold in Japan. Re-Entry Permits: Processes permits needed when leaving and re-entering Japan during a valid residence period. Status of Residence Certification: Issues formal certification confirming your current residence status for official use. Regional Offices: Operates immigration bureaus across Japan, not only in Tokyo, for in-person applications. How to Get Started: Identify your current residence status and what change or extension you need. Visit isa.go.jp to check the specific documents required for your case. Submit your application at the regional immigration bureau covering your address. Apply for extensions well before your current status expires — processing isn't instant. Important Notice: Residence status applications must generally be filed before the current period expires — leaving it too late can create real complications with your ability to remain in Japan legally.
