Migration has been a major discourse in the Nepali migrant force at present. There is a growing trend of migration in many countries, including Nepal. Therefore, many student migrants and immigrants are currently relocating in developed countries. This trend has resulted in inflow of remittance in national Gross Domestic Product (GDP) of Nepal. As a result, English language skills incorporate a fundamental requirement for students and immigrants in Anglo-phone countries. Social and economic integration of students and immigrants depend on language ability and skills. This study attempts to explore an association between English language ability and labour market opportunities among students and immigrants currently residing in the USA, the UK, Australia and Canada. In this regard, this study proposes to explore how language ability and labor market opportunities are related in achieving sustainable socio-economic integration of Nepali immigrants in developed countries. The study applies mixed method research design. At the same time, secondary data from the previous scholarships have been employed to bring the conceptual framework. The guidance of professors, supervisors and scholars has also been taken as reference. The language skills and ability encapsulate job opportunities. Consequently, the study stems from the sustainable social and economic transformation of immigrants in the Anglosphere.
