IN THIS GUIDE · Turning an internal apprenticeship record into evidence of work actually performed
Start with the L-1B eligibility and application overview
Treat the programme as a record, not a credential
An internal programme is not a licence, and no particular length of training establishes anything by itself. What it can do is document a structured path through the organisation's own methods, with dates, supervisors, and assessments. Obtain the curriculum as it stood when the applicant went through it, the assessment records, and the names of the mentors involved. That gives a reviewer something concrete to follow instead of a programme title. Request three things from the training function in one message: the curriculum as it stood when the applicant went through it, the assessment records, and the names of the mentors involved. Programmes are revised often, and the current syllabus describes something the applicant may never have done. Note also that no particular length of training establishes anything by itself; the record's value lies in the dates, supervisors, and assessments it fixes.
Match each milestone to work that was produced
Place the two records side by side. For each stage completed, identify what the applicant was permitted to do afterwards and what they actually did: the equipment they were signed off to operate, the procedures they were allowed to approve, the tasks they took over unsupervised. Dates and named projects turn a training file into an employment history. Stages that never led to real work should be left out rather than padded into significance. Build the map in two columns: stage completed on the left, work performed afterwards on the right. The right-hand column carries the account, so fill it with equipment signed off, procedures approved, tasks taken over unsupervised, and named projects with dates. Any stage with an empty right-hand column should be dropped rather than padded, because a reviewer reading a list of courses learns nothing about the applicant.
Explain what the training gave that general experience would not
The classification is concerned with knowledge of the organisation's own products, services, and techniques, or an advanced level of knowledge of its processes and procedures. Say plainly what is specific to this employer: internal standards, tooling, sequences, or judgement rules not published anywhere. Generic experience is not enough, and neither is length of service on its own. The point is what the programme taught about how this organisation works. Write the employer-specific part in plain sentences naming what is internal: a sequence used nowhere else, a judgment rule about when to stop a run, a tolerance set by this organisation rather than by a published standard. The classification concerns knowledge of the organisation's own products, services, and techniques, or an advanced level of knowledge of its processes, and length of service alone establishes neither.
Check where the training sits in the qualifying period
Whether time in a training programme counts as qualifying employment abroad depends on the facts of the arrangement, including whether the applicant was employed, by which entity, and what they were doing during it. Set out the dates, the employing entity, and the nature of the engagement, and refer the assessment to licensed United States immigration counsel rather than assuming a period on the programme automatically counts. Hypothetical example: an apprenticeship in high-voltage switchgear commissioning runs three years, with the final year spent on live sites under a named mentor. Whether that period counts as qualifying employment abroad depends on the facts of the arrangement, including whether the applicant was employed, by which entity, and what they were doing. Set out the dates, the employing entity, and the nature of the engagement, and refer the assessment to counsel rather than assuming the period counts.
