Certificate of Eligibility (COE)
The Certificate of Eligibility is the document that says Japanese immigration has already agreed, in principle, that you qualify for a particular status of residence. It is the long step, and it happens entirely inside Japan.
Who applies, and where
The applicant is your sponsor: the company that hired you, the university that admitted you, the spouse or relative you are joining. They file at the regional immigration bureau covering the place you will live.

What happens when it arrives
The certificate is posted to you, usually by your sponsor. You then apply for the visa at the Japanese consulate that covers your state, attaching the original. The visa itself is comparatively quick, and for U.S. nationals it is free.
| Status | Who normally sponsors |
|---|---|
| Engineer / Specialist in Humanities | Your employer in Japan |
| Student | The school or university |
| Spouse of a Japanese national | Your spouse |
| Dependent | The family member you are joining |
How long it takes, realistically
Immigration bureaus in Japan publish processing times that vary by status and by region, and the practical answer for most applicants is between one and three months. Applications filed in the weeks before the April and October intakes take longer.
The certificate has a validity of three months from issue. If it expires before you use it, the whole application starts again in Japan.What you do while you wait
Gather your side of the file, which is short: passport, form, photo and proof that you live in the consular district. Confirm which office covers your state, because three of the districts are split in ways that surprise people.
When it arrives
Take the original. Consulates want the document itself, not a scan, and the sponsor in Japan normally posts it by courier for that reason. Once it is in your hands, the visa is a matter of a few working days, and for a U.S. national it is issued free.
