Is it troublesome to immigrate to Australia alone? What's the procedure and how much will it cost?

It's hard to do immigration directly ~ ~ and you are neither a skilled immigrant nor an investment immigrant ~ ~ ~ You spend a lot of money, and skilled immigrants get four sevens. It's very demanding now. If you have more economic strength, you can consider investing in immigrants, but this is more painful. You can't guarantee that you can do it for millions ~ ~ ~ You'd better study abroad and handle it slowly.
