Vendor credentials may show training but should be connected with the actual company knowledge claimed.
Explain the company application
Use appropriate configuration, process and work examples showing the employee’s role. Do not present a public certification as if it described every internal method or the applicant’s personal contribution.
Build an evidence chain from general training to company-specific application. Vendor certificates may establish course completion; pair them with internal configuration records, authored procedures, project histories, access logs, training materials and knowledgeable manager statements explaining the employee's contribution. Redact genuine confidential details where appropriate rather than replacing them with vague praise. The legal inquiry is whether the worker possesses special product knowledge or advanced understanding of company processes, not whether the vendor issued an expensive badge. Also document a continuous qualifying year abroad during the relevant three years and the operating affiliate, subsidiary, parent or branch relationship. The common mistake is submitting certificates with no bridge to the proposed US services.
Hypothetical example: A controls specialist at a Bégin wood-drying kiln manufacturer holds a public automation certificate. She also created the employer's kiln-startup sequence and diagnosed failures using an internal library. Her file can include version history, sanitized work samples, supervisor explanations and the US assignment plan. These records distinguish her company learning from skills available to every certificate holder.
