Oak Admin Office is a Certified Administrative Procedures Legal Specialist Office (Gyoseishoshi). We are nationally licensed to prepare legal documents and represent clients in immigration procedures. Please note: While we use the term "Immigration Lawyer" (the official English designation by the Gyoseishoshi Federation), we are not Attorneys-at-Law (Bengoshi) and do not represent clients in court disputes.

We utilize our professional expertise to maximize the likelihood of a successful application. However, please understand that final decisions on visas and licenses are the sole discretion of the Japanese government. Therefore, we cannot guarantee specific outcomes or approval times.

The content on this website is for general informational purposes. As Japanese immigration laws change frequently (such as the October 2025 amendments), please contact us directly for advice regarding your specific situation before taking action.

Visiting this website, using our contact forms, or receiving a preliminary email response does not create a professional client relationship. A formal relationship is established only upon the signing of a Service Agreement and payment of the relevant fees.
