This paper offers reflections on how guidance professionals can support young people interested in learning mobility and what skills they need to encompass to provide such service. Guidance professionals can play a key role in creating good conditions for a stay abroad, they can also contribute to increase the numbers taking part in periods of learning mobility and open up the opportunities for underrepresented groups. This paper argues that easy-access and high-quality mobility guidance throughout the whole education system may help pupils and students realise how mobility could optimize their learning, life and career paths, and that performing such guidance requires training and competence enhancement. The topic discussed in this paper is what skills guidance professionals need to be able to assist young people gaining personal growth through sojourn or studies abroad?
