Industrial Trainee

The status code is E9, and it covers non-professional manual work, that is, manufacturing, construction, agriculture and fisheries, and services (Employment Permit System).

People registered under the Industrial Trainee (D3) status number 931, which is 0.1% of all registered foreigners. Compared with 2,516 in 2015, 10 years earlier, that is a decrease of about 63%. The largest nationalities are China at 35.8%, Vietnam at 19.7%, and Korean-Chinese at 11.8%. They are found in 126 districts, and the largest counts are Gimhae-si with 100, Yangsan-si with 49, and Gumi-si with 37.

Note: the status families are exactly as the yearbook groups them. The overseas Korean status (F-4) does not appear on this page. Its holders file a place-of-residence report rather than a foreign-resident registration, so they are outside the registered foreigner statistics; they are not absent from the country. On the staying basis they were the largest single status in 2025, at 556,288.

The 6 groups sum to 1,604,920, the same as all registered foreigners.

Note: a family is the sum of the statuses inside it, so adding a family together with its individual statuses counts the same people twice.

The jade bar is the E group, which contains Non-professional Employment.
