How are most illegal immigrants coming to Spain?

Most illegal immigrants coming to Spain primarily arrive by sea from North Africa, particularly from countries like Morocco and Algeria, often using small boats or makeshift vessels. Others enter through land routes, crossing the borders of Ceuta and Melilla, two Spanish enclaves in Morocco. Additionally, some individuals may overstay visas or enter through legal channels and subsequently remain in the country illegally. Economic hardship, political instability, and the search for better opportunities drive many to undertake these perilous journeys.
