TtiGer大人请进，TAFE毕业后签证有多7个月时间申请TR？

看到DIAC官方文件这样一段话：Overseas students currently enrolled in a trade course will have been given seven months since the Minister’s announcement to either lodge a visa application or to increase their English language skills prior to making a GSM visa application.是说TAFE毕业后签证有多7个月时间申请TR？这是个什么签证啊

字面意思是说在TAFE毕业即学生VISA到期之前而不是之后，不太明白这段没头没脑的话是什么意思。好像是说TAFE学生通常需要7个月的时间来准备IELTS和移民申请。。。有点断章取义了，问问高人吧

这句话的出处是移民局关于TAFE毕业生申请移民雅思要求提高的公告，该公告是上半年公布的，原文如下：

Will there be transitional arrangements for overseas students?
There will be no transitional arrangements for overseas students enrolled in trade courses.
Overseas students currently enrolled in a trade course will have been given seven months since the Minister's announcement to either lodge a visa application or to increase their English language skills prior to making a GSM visa application.

这句话的意思是：
目前在读TAFE的海外学生，到实行新政策前有7个月的时间
按照目前政策（没有提高英语要求）申请，或者
提高英语技能
