BACKGROUND: Live-in migrant caregivers have been employed in various developed countries to meet the growing demands of long-term care needs for older adults. Increasingly, nurses in these countries are involved in providing caregiving training to these live-in migrant caregivers. A comprehensive understanding of the caring experiences of these live-in migrant caregivers can better support their caregiving experiences and improve their quality of care. AIM: To synthesise the experiences of live-in migrant caregivers for older adults requiring long-term home care. DESIGN: Qualitative systematic review using meta-ethnography. METHODS: PubMed, CINAHL, Embase, Google Scholar, PsycINFO, Scopus, ProQuest and Web of Science Core Collection were searched from inception to November 2024. Qualitative studies that explored the experiences of migrant caregivers providing live-in care to older adults requiring long-term care were included. Two reviewers screened the articles according to the eligibility criteria, appraised the articles using the Critical Appraisal Skills Programme Tool, and extracted qualitative data independently. Data synthesis was performed using Noblit and Hare's meta-ethnography. RESULTS: Five themes emerged from the 14 included studies: beyond caring for the older adult, compromising basic rights, being away, coping strategies, and being a better caregiver. These themes contributed to the overall line-of-argument synthesis: 'Treat me as a human being' so that I can grow and 'give my all' - beyond a transactional paid job to provide care. The synthesis revealed the vulnerabilities, challenges, opportunities, and capacity development encountered by live-in migrant caregivers in unleashing their potential to be better caregivers. CONCLUSION: The findings highlighted the complexities of care intertwined in social structural bounded relationships between live-in migrant caregivers, older care recipients, and employers. Greater advocacy is needed to embrace live-in migrant workers as valued care providers of the eldercare workforce. Nurses have a role in promoting the development, delivery, uptake, and evaluation of structured, culturally contextualised and comprehensible long-term care training programs for live-in migrant caregivers and their employers. Significant opportunities could be provided to equip live-in migrant workers in caregiving roles, ensure and allocate time to rest, communicate their caregiving needs and moderate employers' expectations. Enhancing the quality of caregiving, improving their intertwined relationships and exercising cultural sensitivity contribute to better caregiving experiences and well-being for older adults, migrant caregivers, and employers. REGISTRATION AND REPORTING CHECKLIST: The study protocol of this review was registered in PROSPERO (CRD42023392767). The eMERGE meta-ethnography guideline was adhered to.
