Recent surveys of international business professionals indicate that foreign language abilities and cultural sensitivity are important competitive advantages in today's globalized economy. The current study interviewed 71 practicing global professionals currently working in cross border transactions in diverse fields. Biographic, demographic and second language data were collected, including information on experiences and opinions on the use and importance of foreign language and cultural awareness abilities in the professional world. Research questions include: (1) Who are the global professionals applying L2 abilities at work? (2) How do they apply these abilities? (3) What are the profiles of advanced and non-advanced proficiency users? (4) How important are linguistic abilities and how much of a competitive advantage do they represent? (5) What language strategies and communication strategies are used? (6) What are the most common beliefs on the role of foreign languages and culture awareness in business? (7) How well do intercultural communication models explain the culture views and experiences reported by working professionals? Results indicate that learners with self-reported advanced proficiency regularly apply the four language abilities (listening, reading, speaking and writing) at work, albeit in varying degrees, depending on the level of complexity of the task (phone, email, face-to-face meeting, etc.). For the majority of informants, foreign language and culture abilities are considered important for professional effectiveness. For those who reported advanced foreign language abilities, they also exhibited a greater appreciation for increased exposure to foreign language learning, had received more foreign language instruction, and had more experience working and living abroad. Those advanced in foreign language abilities were also more likely to be non-native speakers of English, have earned a university degree while using an L2, had family or community connections to the target language, have emigrated, or have a spouse with a different L1. The study also ranks and identifies the informants' strategies used to deal with language and culture issues. Participants' anecdotes were analyzed in light of current cultural analysis models applied in International Business Communications. Suggestions are presented for curricula changes to improve foreign language proficiency in professional settings. / text
