The importance of culture for ensuring safe and high-quality nursing care cannot be overstated. However, despite the increase in nurse migration, the concept of acculturation in nursing has not been well defined. This study aimed to elucidate the concept of acculturation in immigrant nurses.

The defining attributes of the concept were established using Walker and Avant's 8-step method. This article is due to the dissertation of the PhD degree course approved and defended at the Faculty of Nursing, Baqiyatallah University of Medical Sciences. In this study, the researcher started collecting data after receiving the Code of Ethics (IR.BMSU.REC.1401.114) from the Iran National Committee for Ethics in Biomedical Research. The researcher provided the participants with contact information and was always ready to answer their research queries.

Without any time constraints, a search was conducted on databases including Scopus, Pub Med, Web of Science, SID, Magiran, Irandoc, and Oxford Medical Dictionary using the keywords 'acculturation' and 'immigrant nurses'. Atotal of 18 articles were analyzed based on the inclusion criteria.

Immigrant nurses experience acculturation through two main attributes. One-way acculturation involves the impact of social values, norms, customs, and habits on the nurses. Two-way acculturation refers to the cultural exchange between the nurse and the new environment.

According to the study, immigrant nurses experience acculturation as being impacted by various aspects such as beliefs, values, norms, behaviors, and habits.
