最近移民局开始对技术移民大放水，很多收到491邀请的小伙伴都开始心痒痒的要换189 190， 直接拿PR。这可能么？
志杰移民告诉大家，这是对一部分人是可能的。但是不是所有人都能符合条件。
491收到邀请的人分为以下几种类型
1 491已经收到邀请，但是还没有递交491签证。 在这个同时又收到了189或者190的邀请。
这种情况可以无脑转换，可以直接递交189或者190的申请。
2 491 已经递交了，但是还没有下签。
这种情况也可以递交189或者190签证，就是要多付一次189/190的签证费。
3 491 已经下签了。 这种情况就比较tricky.
189.224A 是这么规定的
189.224A
(1) If, at the time of application:
(a) the applicant is the holder of a Subclass 491 (Skilled Work Regional (Provisional)) visa or a Subclass 494 (Skilled Employer Sponsored Regional (Provisional)) visa; or
(b) the last substantive visa held by the applicant was a Subclass 491 (Skilled Work Regional (Provisional)) visa or a Subclass 494 (Skilled Employer Sponsored Regional (Provisional)) visa;
the applicant must have held that visa for at least 3 years at the time of application unless circumstances specified in an instrument under subclause (2) exist.
(2) The Minister may, by legislative instrument, specify circumstances for the purposes of subclause (1).
如果想转换 189 签证，就要绕开189.224A条款
190.215A也有类似的规定
190.215A
(1) If, at the time of application:
(a) the applicant is the holder of a Subclass 491 (Skilled Work Regional (Provisional)) visa or a Subclass 494 (Skilled Employer Sponsored Regional (Provisional)) visa; or
(b) the last substantive visa held by the applicant was a Subclass 491 (Skilled Work Regional (Provisional)) visa or a Subclass 494 (Skilled Employer Sponsored Regional (Provisional)) visa;
the applicant must have held that visa for at least 3 years at the time of application unless circumstances specified in an instrument under subclause (2) exist.
(2) The Minister may, by legislative instrument, specify circumstances for the purposes of subclause (1).
同理，要想申请190签证就要绕开 190.215A 条款。
理论上讲，可以用一个其他的签证来覆盖掉491签证。可以选的签证一般是500签证。
如果可以批准一个500签证。那么就可以转换189或者190的申请。
但是这么做也不是完全没有风险的。
风险在于 500 学生签证也未必能给批准，申请491签证的人可以认为有移民倾向，和500签证拿到后未必还能收到189或者190的邀请。
