Objective: This study examined these constructs among foreign nurses in public hospitals in the Northern Border region of Saudi Arabia. Methods: A cross-sectional quantitative design was used. Total population sampling was applied to foreign nurses working in 12 secondary and tertiary hospitals among 501 nurses. Data were collected using three validated instruments assessing work performance, organizational commitment, and job satisfaction, ensuring the reliability and construct validity of the measured variables. Descriptive statistics were computed, and independent t-tests and one-way ANOVA were used to examine differences by demographic profile. Results: Foreign nurses reported high task and contextual performance and low counterproductive work behaviour, indicating generally strong performance levels. Organizational commitment was moderate, with affective and normative commitment slightly higher than continuance commitment. Job satisfaction was also moderate: supervision, nature of work and coworkers had the highest mean scores, whereas fringe benefits, communication and operating conditions were lowest. Most dimensions of performance, commitment and satisfaction did not differ significantly by age, gender, education, area of assignment or length of service. Significant differences were observed only for counterproductive work behaviour and communication by hospital level, and for promotion and fringe benefits by nationality. Conclusion: Foreign nurses in this region appear to function at a high-performance level and display moderate organizational commitment and job satisfaction, with particular strength in intrinsic and relational aspects of work. Dissatisfaction is concentrated in structural and financial domains, and meaningful variation is driven more by hospital level and nationality than by basic demographic characteristics
