Teachers trained in one country are often not allowed to serve as teachers in another country because their teacher's license is not recognised as equivalent. The barriers these teachers have to overcome in order to work in their profession again are high and often require further (full) teacher training at the university. The paper provides insights into the conditions for teachers who participate in (re-)qualification programmes in Germany and Europe. By linking the theoretical concepts of a biographical approach to teacher professionalisation and transnationalisation in education, the results of an interview study with teachers who have participated in a programme for refugee teachers at a university in Germany are presented. The Grounded Theory analysis reconstructs the strategies of internationally educated teachers managing to keep up their hope to be able to work as teachers again and thus counter the formal de-professionalisation they are facing.
