北领地491海外申请条件变了?

刚看了北领地官网,北领地491是不是明确要求海外申请人都必须有job offer?还是说只有某些职业要求job offer?哪位能给看一下?谢谢!

不是必须,是有的职业会需要

If the NT Migration Occupation List requires it, evidence of a full-time employment offer in your nominated occupation or in a closely related skilled occupation.

如果你的职业comment里有要求才要
比如这样的字眼Offshore applicants must provide evidence of having received an offer of employment by a NT employer in their nominated occupation or a closely related occupation

好的谢谢
