5. Results
Language tourism is one of the new and growing areas in the world, which can affect other tourism areas and be greatly affected by it. In this research, the opportunities for the development of Persian language tourism are carried out with the approach of interactive sociolinguistics. This approach is important for application in language tourism. Interactional sociolinguistics in language teaching emphasizes a kind of intercultural communication to understand the language of the audience. Gumpers (1982) defined the methodological approach of interactional sociolinguistics as generally focused on face-to-face interactions where there are significant differences in the socio-linguistic background of the research participants, and social interactions through analysis. The analysis of linguistic, anthropological and sociological perspectives that are intertwined examines the construction of a linguistic sign that has a qualitative and interpretative approach. The first main category was called local-regional opportunities, which included two subcategories of promoting cultures and introducing different dialects of Iran. The second main category was called national-social opportunities, which included five sub-categories of strengthening and interdependence of society, historical, religious, artistic and literary richness of Iran.  
The third main category was called international development opportunities, which included two subcategories of producing attractive content and appropriate interactions with other countries. The fourth main category was called environmental opportunities, which included two subcategories of suitable geographical situation and various natural attractions. The fifth main category was called economic opportunities, which included two subcategories of economic improvement and affordability. The sixth main category was called growth and development opportunities, which includes three subcategories of proper Persian language education, training of qualified Persian language teachers, and comprehensive development of the tourism industry.
