Abstract:
This study sought to find out relationship between illegal migrant and notable threats to the national
security. The specific objectives of the study were to examine the trends of illegal immigrants in
Tanzania, to determine the relationship between illegal immigrants and notable threats to the
national security and to forecast the presence of illegal immigrants in for the five years ahead. The
study was guided by rational choice theory whereas the study used quantitative research approach
whereas the study used secondary data from immigration reports. Data were analysed using
regression analysis. The study found that the analysis demonstrated a statistically significant
positive correlation between the number of illegal immigrants and notable threats to national
security. This finding underscores the need for comprehensive strategies to manage and mitigate
potential security risks associated with illegal immigration. Furthermore, the study employed
descriptive statistics which included frequencies, percentages, and means, while inferential
statistics included Pearson's correlation and multiple regression analysis. The results of the
forecast suggest a continuous and incremental increase in illegal immigration over this period,
culminating in a projected total of 31,903 illegal immigrants by the end of 2028. This projection
highlights the persistence of the issue and the necessity for proactive policy measures. The study
recommended that the Tanzanian government should prioritize strengthening border security
measures to curb the influx of illegal immigrants. This includes bolstering surveillance, investing in
modern border control technologies, and increasing law enforcement presence in high-risk areas.
Policymakers should consider reviewing and reforming immigration policies and regulations to
address the challenges posed by illegal immigration. A comprehensive and adaptable policy
framework is needed to respond effectively to changing dynamics.
