This study examines selection and influence related to delinquent behaviors of immigrant and nonimmigrant adolescents attending three majority-immigrant schools (54% to 65.2% immigrant) and four minority-immigrant schools (11.1% to 25.1% immigrant) in one community. The sample included 1,169 youths (50.4% male; 24.2% immigrant) initially between the ages of 12 and 16 years (M =13.92, SD = 0.85). Results showed that immigrant and nonimmigrant adolescents were similar to their peers on delinquent behaviors, and peer selection and social influence operated in a complementary manner to explain this similarity. The processes did not differ between immigrants and nonimmigrants or between school contexts, suggesting that immigrants do not differ from nonimmigrants on either the prevalence or the processes behind delinquency.
