Can't believe the exact nationality, however something similar has happened, the pilot, a citizen from an EASA MS, completed all his training in his home country, from ppl, hours, atpl exams, Cpl / IR, and as his medical was issued by his home NAA, his home NAA issued his licence.
He secured a job based in the UK flying for a UK airline pre-brexit, a condition attached to the employment, was that his licence would need to be transferred to the UK and he did a SOLI transfer of his medical records / licence to the UK CAA.
He was recently made redundant, and although he had the right to remain / work in the UK, has decided to return to his own country, however to work in his own country he needs a licence issued by EASA with no easy route to transfer !
