Come into my world

When is the person going to coming into my world?

I think the above sentence is wrong, it should be come into my world.

Thanks.

You are right.
Alternatively:
When is the person coming into my world.

I’m not sure what you mean by it, though.

Thanks. I saw this in a Taiwan English Yahoo website and I was curious. I don’t know the exact meaning but treat it as a way to learn. Thanks again.
