After you graduate from undergraduate course, you can consider applying for the admission notice of postgraduate diploma course in local public institutions to apply for a visa, and then decide whether to transfer to a junior college course. The requirement of junior college is usually IELTS 6, and the single subject is not less than 5.5. If you have an IELTS score that meets the requirements, you can go directly to junior college courses without taking language classes. Even if you don't meet the IELTS score required for major entrance, you can consider applying for both language and major admission. After completing the language course in the local area, you can enroll in this major.
After completing at least two years of junior college courses, you can get a three-year work visa after graduation, and you can get immigration status through experience category after one year of work.
