The purpose of this study was to explore and document the migratory motivations and reasonings of Mexican mothers of autistic children pursuing autism services in the United States. The study was guided by the overarching research question, "What are the experiences of mothers living in the U.S./Mexico border while seeking services for their autistic children, and what social and financial resources influence their decisions?". Following a Community-Based Participatory Research approach, we collaborated with organizations and stakeholders in the development of qualitative research materials while also supporting the purposeful recruitment of caregivers who: (1) had lived in the U.S./Mexico border and moved to the United States to pursue autism services, or (2) were currently living in the U.S./Mexico border and were looking to pursue autism services in the United States. Eleven mothers participated in a two-part semi-structured interview protocol alongside a demographic form. Findings outline three global themes that describe the dynamic process of pursuing autism services and migrating to the United States: (1) stage of constant contrast between Mexico and the United States, (2) active pursuit of autism services in the United States, and (3) potential pathways to immigration. The global themes provide a systemic analysis and reflection of the current autism service system in Mexico while also highlighting the gaps in service coordination for first-generation immigrant families.
