Hi, this is a great subject. Topics associated with cross-cultural communication include various contexts or settings -- for example, cross-cultural communication in the classroom, in international business, in politics, etc.
Are you interested in education? If so, you can write about how cultural differences create misunderstanding in the classroom. For example, the curriculum might have a "cultural bias."
You can also make a topic of choosing particular cultures -- for example, Latino culture and American culture.
Choose a topic related to your interests. What would you like to do professionally as an adult?
