Accommodation theory also possessed practical applications in the development of learning a second language. This was seen when the student's education of and proficiency in said language was either assisted or hindered by accommodative measures. Giles, Coupland, and Coupland (1991) also addressed the part that accommodation theory plays in a situation they called "language switching", when bilingual individuals must decide which language they should speak when they are in an organizational environment with other bilingual individuals. This can be an incredibly important choice to make, especially in a business setting, because an incorrect judgment in this area of communication could unwittingly promote negative reactions between the two or more parties involved. In addition, accommodation theory was strongly intertwined with the way an immigrant accepts and is accepted by their host country. An instance of over-accommodation from the immigrating individual can unintentionally damage that person's sense of individuality while a strong divergence from the immigrating individual from their host culture can prompt the natives of the host country to react negatively to them because of the immigrating individual's use of divergence.
