Study used 357 Singaporean managers to document their availability for international assignments and their international aspiration. To understand factors that affect their international aspiration, we investigated the impact of family, career, culture and host country factors and personal entrepreneurial characteristics on mangers' international aspiration and willingness to accept international assignment. Overall, results show that family, spouse and children and personal characteristics influence both the degree of willingness travel and determinants of managers' attitude toward international assignments. Career and attitudes of spouses will likely have a significant impact on managers' willingness to accept international assignments. Prior cross-cultural international experience and personal entrepreneurial characteristics are also important factors that influence managers' willingness to accept international assignments. Implications for research and practice are also discussed.
