The objective was to improve the effectiveness of collaboration among teachers who are both national and expatriate in the AI KG schools. There were three sub-questions to answer in the study, conducted using the qualitative phenomenological technique. Semi-structured interviews were used to gather data for this research. There were five native teachers and five expatriate teachers that participated in the discussion. Audio files were used to store the information gleaned from the interview. After that, the NVIVO application version 1 0 was used to clean, inspect, code, and analyze the data. For both native and expatriate instructors, the study found that collaboration is essential for success. Further evidence was found to support the incredible impact of collaboration, particularly when it comes to helping students learn a new language. Aside from that, researchers discovered what factors made the team more productive and what obstacles they faced were impeded.
