Continuing a discussion with @tando here:

Bad news about getting an APRC for dependents

2 is just exempted from Paragraphs 1 and 3 of Article 46, Article 47, Article 52, Paragraphs 3 and 4 of Article 53, Subparagraph 5 of Article 57, Subparagraph 4 of Article 72 and Article 74, and the employment security fees. In addition to the exemptions, 1,3,4 can get open work permit.

About article 51 of the Employment Service Act, the act that gives us the open work permit. Full text:

So I looked up those exemptions in the article, and that created more questions. The first:
Paragraphs 1 and 3 of Article 46
Text of Article 46

Article 46

Unless otherwise provided in the Act, the work that a foreign worker may be employed to engage in within the Republic of China is limited to the following:
1.Specialized or technical work.
2.Director/manager/executive of a business invested in or set up by overseas Chinese or foreigner(s) with the authorization of the Government of the Republic of China.
3.Teacher at the following schools:
(1)Teacher at a public or registered private college/university or school established especially for foreign residents.
(2)Approved teacher teaching course(s) on foreign language(s) at a public or registered private primary or high school.
(3)Teacher teaching course(s) at a public or registered private experimental high school’s bilingual department or at bilingual school(s).
4.Full-time teacher at a short-term class registered for supplementary schooling in accordance with the Supplementary Education Act.
5.Sports coach and athlete.
6.Religious, artistic, and show business work.
7.Crew member of a merchant vessel, working vessel, and vessel ad hoc permitted by the Ministry of Transportation and Communication.
8.Marine fishing/netting work.
9.Household assistant and nursing work.
10.Workers designated by the Central Competent Authority in response to national major construction project(s) or economic/social development needs.
11.Other specialized workers ad hoc approved by the Central Competent Authority due to the lack of such specialist in the domestic employment market and the business necessity to retain the service of such specialist
The Central Competent Authority shall consult the other central competent authority(ies) administering the work concerned to determine the working qualification(s) and standard of review thereof in respect of the foreign worker engaging in work as referred to in paragraph 11 of this article, except for as otherwise provided by other laws.
The employer when employing a foreign worker to engage in work as referred to in subparagraphs 8 to 10 of paragraph 1 of this article, shall execute a labor contract in writing with the employed foreign worker and with fixed duration only; in case where it is not so fixed, the duration of his/her employment shall be deemed as the same with the duration of employment permit thereof. The foregoing in this paragraph shall equally apply in the case of extension of such labor contract.

I think paragraph 1 is the list of jobs, and paragraph 3 is the last paragraph, so what restriction does paragraph 2 still place? If a job requires that a foreigner have 2 years of experience, does that still apply? Am I misunderstanding paragraphs?

Does having an open work permit exempt me from all of the Employment Service Act?
