Students of local institutions qualify only if their institution appears in Schedule 1 to Cap. 608: the statutory universities and the Academy for Performing Arts, registered post secondary colleges (Cap. 320), Vocational Training Council bodies (Cap. 1130) and, for post secondary programmes only, schools registered under the Education Ordinance (Cap. 279). A school leaver taking a summer job after the HKDSE is not a work experience student, even with a university offer in hand, because enrolment must exist when the employment starts.
Hong Kong residents at non-local institutions qualify under the non-local programme limb, provided the full-time programme leads to a degree or higher. An overseas undergraduate not resident in Hong Kong fits neither definition, so the minimum wage applies, and visitor conditions of stay rule out any employment, paid or unpaid, without an employment or training visa. The host must inspect the travel document of any non-permanent resident under section 17J of the Immigration Ordinance (Cap. 115), and section 17I punishes employing anyone not lawfully employable.
Non-local students at Hong Kong institutions work under the No Objection Letter issued by the Immigration Department. Internships must relate to the curriculum and be arranged or endorsed by the institution, capped at one academic year or one third of the programme length, whichever is shorter, at undergraduate level and above. Sub-degree students are limited to mandatory placements of up to six months, and exchange students generally cannot take internships. Temporary relaxations exist for degree students, so the internship agreement records the letter's actual conditions.
