A study by Tung (1987) across 80 US MNCs had identified four general categories which may contribute to expatriate success. These categories are (1) technical competence, (2) personality traits or relational abilities, (3) environmental variables, and (4) family situations. Later, by examining 15 organisations, Ronen (1989) as cited in Chew (2004) developed a model, for an effective selection, that consists of five categories: (1) job factors, (2) relational dimensions, (3) motivational state, (4) family situation, and (5) language skills.
