Migration is a multifaceted and transformative experience that challenges individuals on various fronts, with language serving as a critical facet of this journey. This study delves into the intricate relationship between language and mental health during the migration process. It examines how language proficiency, language barriers, and linguistic acculturation significantly influence the psychological well-being of migrants. The paper draws from a comprehensive review of existing literature and presents empirical evidence gathered through surveys and interviews with migrants from diverse backgrounds. Findings reveal that language proficiency positively correlates with improved mental health outcomes. Migrants who acquire proficiency in the host country's language experience lower levels of stress, depression, and isolation. Conversely, language barriers can lead to a sense of alienation, reduced access to essential services, and increased psychological distress among migrants. The abstract also explores the concept of linguistic acculturation, highlighting the tension between preserving one's native language and adopting the language of the host country. Understanding the profound impact of language on mental health during the migration experience is essential for policymakers, healthcare providers, and social support organizations. This research underscores the importance of language education and cultural sensitivity in facilitating a smoother migration process and enhancing the well-being of individuals and families embarking on this transformative journey.
