Immigrants have poorer health outcomes due in part to limited access to health care. Children with autism spectrum disorder (ASD) who have immigrant parents are diagnosed at a later age and those whose parents have limited English proficiency receive fewer hours of services. What contributes to these health care and support services disparities? This review examined eight qualitative studies published between 2010 and 2020 that explored barriers experienced by immigrant parents of children with ASD with regard to accessing diagnostic and/or intervention services. Key barriers included long wait times, language barriers, and limited health literacy. Recommendations for practice and future research are discussed.
