Becoming a new student in a place far from the closest people, such as parents, is a challenge that some UKSW students must face. Apart from differences in culture and language, new students also need to adapt to changing habits, studying methods, time management, and finances. Students who are immigrants from areas outside Salatiga City need to get used to living life independently. These things can become stressors for them, thus affecting their mental state in learning and socializing. Not only immigrant students, conditions of disturbed psychological well-being can also occur in students originally domiciled in Salatiga. Even though they live close to their families, it does not necessarily make them avoid the stress of being new students. Stress that is not appropriately handled can affect a person's psychological well-being. Psychological well-being is closely related to self-acceptance, starting positive relationships, independence, environmental mastery, self-development, and life goals. Purpose: This research aims to find out the difference in the level of psychological well-being in new arrivals and native Salatiga students in the class of 2021. Method: This research uses a quantitative method with a comparative approach. The population in this study are new students from batch 2021 who come from outside Salatiga and are originally domiciled in Salatiga, with 195 students each. So, the total number of respondents was 390 students. Data were analyzed using the Mann-Whitney U T-test (p-value 0.483 <0.05). Results: The results of the Mann-Whitney U test show p = value 0.483 <0.05, meaning there is no difference in the psychological well-being level of new students from outside and native. Conclusion: There is no difference in psychological well-being among new arrivals and native Salatiga students in the class of 2021, both of whom have moderate to high PWB levels.
