Kelantan police report a significant factor driving illegal immigration to Malaysia is established family networks. The police chief highlighted this trend particularly among Rohingya migrants. These networks provide crucial support, including assistance with settlement, upon arrival in the country. Relatives already in Malaysia offer a vital lifeline for newcomers navigating the challenges of illegal entry and establishing themselves. This suggests existing migrant communities are facilitating further undocumented arrivals. Authorities are analyzing this information to better understand and address the patterns of illegal immigration. The findings underscore the importance of considering social networks when formulating immigration control strategies.
