<![CDATA[This The Indonesia–Malaysia border area is a strategic region that is vulnerable to various threats such as immigration violations, smuggling, and transnational crimes. In this context, the involvement of immigration officers in community service plays a crucial role in strengthening national defense through educational and collaborative approaches. This community service aims to describe the role of immigration officers in educating border communities and building solid cooperation to raise awareness of the importance of safeguarding national sovereignty. The method used in this service is a literature review, analyzing various relevant sources such as academic journals, policy reports, and official documents related to immigration functions in border areas. The results show that the educational approaches conducted by immigration officers have increased public understanding of immigration regulations and the risks of legal violations, while cross-sectoral collaboration has strengthened surveillance networks and early detection of potential threats. These findings affirm that national defense in border regions does not rely solely on security forces, but also requires the active participation of well-informed communities who are concerned about immigration issues. Therefore, the development of educational programs and the reinforcement of collaboration between immigration officers and local communities should be continuously enhanced to ensure sustainable border security.]]>
