Summary

We are seeking an HR & Immigration Coordinator to support critical HR operations across immigration, onboarding, temporary workforce administration, and employee recordkeeping. This role will serve as a key liaison between HR, Operations, staffing agencies, external vendors, and immigration counsel, helping ensure that employee documentation, compliance-related processes, and HR communications are accurate, timely, and well-organized.

Reporting to the Manager of HR, the HR & Immigration Coordinator will help manage employment-based immigration documentation, temporary-to-permanent employee conversions, onboarding logistics, personnel records, and related HR administrative processes. AOI operates across U.S., Taiwan, and China locations and supports a substantial temporary labor population through staffing agency partnerships. The ideal candidate is organized, responsive, and detail-oriented, with the ability to support high-volume HR operations by managing recurring deadlines, maintaining accurate and confidential documentation, communicating clearly, and following through consistently.

Job Responsibilities

Immigration & Compliance Support

• Provide administrative support for employment-based immigration processes (e.g., document collection, tracking, and coordination with legal counsel).
• Maintain organized and compliant immigration records and employee documentation.
• Assist with preparation of internal documentation related to visa sponsor ships, transfers, and compliance tracking.
• Prepare employment verification letters, visa support letters, and invitation letters for business visitors and immigration-related purposes.
• Assist with preparation of employment letters for visa petitions, transfers, and internal documentation needs.

Temporary Workforce & Conversion Administration

• Administer the full conversion lifecycle from temporary to full-time status: distribute and track non-exempt performance reviews, review evaluation outcomes (pass, extend, or fail), initiate background checks, and prepare conversion documentation. This is a high-volume, recurring process that directly affects production headcount.
• Review background check results and escalate discrepancies or concerns to the appropriate HR leader promptly.
• Track probation review timelines and respond to inquiries from supervisors and employees. Delays in this process affect both the employee experience and operational planning.

• Prepare and coordinate welcome materials for new employees and company visitors, including branded items and gift sets.
• Ensure all new hire documentation is complete and properly filed by the employee's start date.

General HR Administrative Operations

• Maintain employee personnel files (electronic and physical) with accuracy, completeness, and compliance with retention requirements.
• Prepare, submit, and track purchase orders for HR-related expenses, including vendor services, immigration costs, and departmental events. Coordinate invoice documentation and ensure proper approvals before submission to Accounting.
• Perform routine filing, document scanning, and record retention activities. Support general office administration for the HR function, including supply coordination and documentation management.

Program & Event Coordination

• Coordinate HR-related events and programs, including quarterly employee events and orientation sessions, managing logistics end to end.
• Support workforce engagement initiatives and internal communication activities as directed by HR leadership.
