The study investigates a policy that has been implemented by the Saudi government since July 2017, which introduced a new tax package for dependents of expatriate workers, focusing on its impact on the Palestinian community in Saudi Arabia, particularly Palestinian millennials. These individuals are part of the second and third generations of Palestinian families who migrated for work in Saudi Arabia. Utilizing autoethnography as a research method, the study narrates the personal experiences that prompted the forced return of this generation to Jordan following the tax imposition. It further examines their psychological acculturation phases and its effects, aiming to illustrate the transformations in their cultural identity before and after relocating to Jordan. The study introduces a novel theoretical framework that conceptualizes acculturation processes as interconnected life stages, with cultural identity acting as a mirror reflecting these changes. The nuances of this identity, characterized by complexity and multilayers, become apparent over time. This study underscores the profound psychological and cultural repercussions of the tax policy on Palestinian millennials, emphasizing the impact on their sense of belonging after departing from Saudi Arabia.
