Filing a visa is one moment; staying compliant is continuous. Statuses expire, roles change, and employers must verify the right to work and keep defensible records. Oak Immigration Services offers a corporate immigration retainer that manages your foreign workforce's immigration status across the whole employment lifecycle, so nothing falls through the cracks.

A low-risk first step
New clients usually begin with a fixed-fee workforce compliance health-check: we load your current foreign hires into our tracker, map every status and expiry, and flag any gaps. You keep the output regardless of what you decide next.
Who it's for
Companies hiring foreign staff in Japan — from growing startups to larger employers with formal HR, Legal and compliance requirements — who want filings handled and their workforce kept legal, tracked, and audit-ready. New hires from overseas are covered by our visa sponsorship service.
