AF Form 3590-1: 20 Year Service Certificate

AF Form 3590-1: 20 Year Service Certificate – Foreign national employees who dedicate two decades of faithful service to the United States Air Force receive special recognition through AF Form 3590-1, the official 20 Year Length of Service Certificate designed exclusively for non-U.S. citizen civilian personnel.

This dedicated form acknowledges the long-term contributions of foreign national (FN) or local national (LN) employees supporting Air Force missions worldwide, often at overseas installations. It forms part of the Department of the Air Force’s broader civilian recognition program, which values loyalty and sustained performance from its global workforce.

What Is AF Form 3590-1?

AF Form 3590-1 is the prescribed certificate for presenting to eligible foreign national employees upon completion of 20 years of service with U.S. Air Force or Department of Defense activities. It differs from the standard AF Form 3590 (used for U.S. citizen civilian employees) to address specific administrative and representational needs for non-U.S. personnel.

The form is one of a series of length-of-service certificates:

  • AF Form 3589 / 3589-1 (10 years)
  • AF Form 3590 / 3590-1 (20 years)
  • AF Form 3591 / 3591-1 (30 years)
  • And higher increments up to 60+ years.

These certificates typically accompany a service pin (lapel emblem) and are presented during an official ceremony, often signed by a wing, group, or installation commander or equivalent.

Who Is Eligible for the 20-Year Length of Service Certificate?

Eligibility targets foreign national employees (also called local national or LN employees in many overseas contexts) who have completed at least 20 years of satisfactory, faithful service with U.S. Forces, typically the Air Force.

Key points from Air Force guidance:

  • Recognition for non-U.S. employees begins at 10 years and continues at 5-year increments.
  • For 20-year milestones and higher (up to 35 years in many guides), the Civilian Personnel Flight (CPF) or Section usually prepares the certificate.
  • The award celebrates continuous, honorable service supporting the Air Force mission abroad.
  • Service computation generally focuses on time worked directly with U.S. Forces; specific rules may vary by host nation agreement or local policy. Supervisors and HR confirm exact eligibility.

U.S. citizen civilians use the standard AF Form 3590 for the same milestone, while foreign nationals receive the “-1” variant.

Purpose and Significance of the Award

The U.S. Air Force values the dedication of its foreign national workforce, who often provide critical continuity, cultural expertise, and specialized skills at bases outside the United States. The 20 Year Length of Service Certificate serves several important purposes:

  • Recognition of loyalty — Two decades of service reflects strong commitment, especially in environments governed by Status of Forces Agreements (SOFA) or host-nation labor rules.
  • Morale and retention — Formal ceremonies with certificates and pins reinforce that the Air Force appreciates long-term contributions.
  • Official documentation — The certificate becomes part of the employee’s recognition history and may support future personnel actions or retirement acknowledgments.

This award aligns with broader Department of the Air Force and DoD civilian recognition programs outlined in guidance implementing DoDI 1400.25, Volume 451, and DAFI 36-1004 (Civilian Recognition Program).

How to Obtain and Present AF Form 3590-1?

  1. Eligibility Verification — The employee’s supervisor or Civilian Personnel Section reviews service records to confirm 20 years of qualifying service.
  2. Preparation — For 20-year awards, the local Civilian Personnel Flight (CPF/CPS) typically prepares the certificate. Organizational units may handle lower milestones (10-15 years), while higher-level signatures apply for 20+ years.
  3. Approval and Signing — A commander (often wing or group level) signs the certificate.
  4. Presentation — The award is presented in an appropriate official ceremony along with the corresponding service pin. This event honors the employee publicly and may include family or colleagues.
  5. Documentation — A copy is usually placed in the employee’s official personnel file.
