Do not assume every site is covered because the employer stays the same. Changed duties, control or service scope may affect the basis of permission.
Compare the next placement before relying on it
Identify the new customer’s actual tasks and supervision and the organizational knowledge used. Preserve the original arrangement for comparison. A delivery deadline or a shared position title cannot provide unrestricted authorization for materially different work.
The order that works is: settle the commercial contract with the client so it describes the company's deliverable, then write the specialized-knowledge case around the employee's role in delivering it, then file. A second employee who could later satisfy the requirements needs a continuous qualifying year with the organisation abroad within the three years before any future petition, and needs genuinely to have acquired the company's internal knowledge, which cannot be conferred by a memo. Confirm as well the employee's continuous qualifying foreign year within the preceding three, the active parent, subsidiary, affiliate or branch relationship and the petitioner's control over any client-site work.
