Specific details for the cases are given below with respect to each of the grounds for deportation.

## (1) Illegal Entry

Among the foreign nationals against whom deportation procedures were carried out for violating the Act in 2009, the number of illegal entrants $ ^{*} $ was 5,373, a decrease of 763 (12.4%) from 2008, which accounts for 16.5% of the total number of foreign nationals violating the Act. Looking at the past history, the number was increasing after 2003, however, it turned into a decrease after 2006. As the percentage of illegally entering persons against the total number of foreign nationals violating the Act is decreasing, it is considered that the effects of measures to exclude them at the border have begun to materialize.

According to statistics by nationality (place of origin), the largest number was from China (1,648 accounting for 30.7% of the total), followed by the Philippines (1,237 accounting for 23.0%), and South Korea (427 accounting for 7.9%), and no movement is seen in the order of these top two countries since 2002. However, the percentage of China is high, which constitutes a significant threat together with its number of cases.
