Welfare differences between Australian skilled immigrants 175 and 176.

Don't trust advertisements, especially those that only leave qq. It's all a lie.

There is not much difference between 175 and 176. Skilled immigrants have a waiting period of two years. As far as I know, it seems that some government preferential courses 176 are not available.

I think you'd better ask immigration. It is estimated that there are not many people who can give you the correct answer, and even if there are, you may not believe it.
