Graduated from college. Living in Australia during menstruation. How do I apply for immigration? Do I need to send an invitation? I went to work there.

If you have work experience, you can apply immediately, and you can apply for skilled migration sponsored by your relatives (provided that the conditions for skilled migration are exempted).

After July this year 1, it seems that the relative guarantee will be cancelled, and the general skilled immigrants can only rely on themselves.

It's too difficult to sign a job. You don't need menstruation. You need a company that is willing to hire you, and it is not easy to recruit people for this position in Australia.
