Amid global income stagnation, rising debt, and inequality, wealth creation behavior (WCB) is vital for economic stability and individual prosperity. This study examined how personal values, career competence, educational attainment, and locus of control (LOC) influence WCB among Nigerian immigrants in Central Indiana, USA. Using a purposive sample of nine respondents aged 38–60 (M = 49.0, SD = 8.32), semi-structured interviews were thematically analyzed within the frameworks of Attribution Theory, the Theory of Planned Behavior, and Hofstede's Cultural Dimensions. Findings showed that resilience, discipline, and familial responsibility promoted financial planning; career competence facilitated adaptability and professional growth; educational attainment was limited by credential recognition and underemployment; and LOC shaped financial strategies, with internal LOC fostering proactive behaviors and external LOC attributing outcomes to systemic factors. The study offers nuanced insights into how international credential recognition, financial literacy, mentorship, and resilience shape the wealth creation experiences of Nigerian immigrants in the United States.
