自从澳大利亚移民和公民事务部对中国学生的澳洲留学570签证类别评审等级调整为3级之后，越来越多的学生因为语言不过关转而申请570类别签证，目的是语言成绩合格后再重新申请本科或者研究生课程。

　　对于报有这样想法并付诸实践的学生， 在4级评审级别的签证要求里，对语言长度有明确的限制，总长度不超过40周; 在3级评审级别的签证要求里，总长度不超过60周。

　　也就是说，如果学生已经通过570签证学了40周的语言课，再申请573类等4级评审级别的签证时，就不能再有语言课程，也就意味着学生必须提交给学校一份满足主课要求的雅思成绩单。

　　以下是澳大利亚移民和公民事务部签证官对以上问题的原文回复，请参考：

　　Under assessment level 4, the student can study a total of 40 weeks of English, this is the total of all English courses undertaken. Therefore, if the student has already undertaken 20 weeks of English, then they are only eligible to study English for another 20 weeks before they reach the total of 40 weeks.

　　I have accessed this information for you from the following :573.234

　　If the applicant is subject to assessment level 3, 4 or 5, the aggregate of the period, or periods, of ELICOS that the applicant is seeking to undertake, together with the period, or periods, of any previous ELICOS undertaken as the holder of a Subclass 570, 571, 572, 573, 574, 575 or 576 visa, or any subsequent bridging visa, does not exceed:

　　(a) for an applicant who is subject to assessment level 3 — 60 weeks;

　　or

　　(b) for an applicant who is subject to assessment level 4 or 5 — 40weeks.
