Mindsets are at least partly determined by character and genes. It also has to do with the policy in an organisation, and how the structure of the office is set up, including the approach of the person in charge. These factors are more the results of experience, education and insight a person gained.
Travel and work placements can, of course, work wonders. These experiences can help us get “under the skin” of a culture. Some would like to say these experiences should be obligatory, but perhaps that is too much to hope for. However, the Life Long Learning Programme provides some opportunities in Europe. Nowadays, employees have their Personal Development Plan, which gives them a chance to develop themselves; mostly by following courses, but working and learning in a different environment would enhance the experience.
In your professional (and personal) experience, do you feel mindsets are learned? Should they be adapted when the work setting demands it? To what extent do mindsets determine your abilities within the setting of an International Office or influence your interaction with international students?

I don’t think you can “learn” new mindsets but you can be made aware of them in a classroom or on a course. Intercultural skills are tools to communicate better with “foreigners”. It’s an attitude you have towards “otherness”, do you reject difference, recognise it, accept it, adopt aspects of other cultures, etc? As international educators we have to prepare students and colleagues for mobility abroad as well as to deal with foreign students, colleagues, administrators in our home institutions who don’t necessarily share our mindset and our way of doing things. So an open mind is essential not only to solve problems but also to anticipate them before they complicate matters or even become serious hurdles.
