Deadlines, tracked
Visa windows, renewals, and city-hall steps with the dates that matter — before they pass.
Documents, organized
Know which documents each step needs, and which you already have ready to go.
Sources you can verify
Every step links to the official page behind it, so you can confirm before you act.
GaijinOS helps organize public information and personal action plans. For legal decisions, confirm with Immigration Services Agency, your city office, or a qualified immigration professional.
