Re: tourist visa convert to either working or student visa
To the OP, what do you want? It's not your sister it's YOU, right?
Since the tourist visa route is nonsense and illegal do you have the money and wish to study without any guarantee that you can stay afterwards. Or do you have the necessary experience to get a work visa legally? But might be not where your sister live (where ever that is).
Would you have a job elsewhere waiting for you or the chance to get one? You need to think about your options, not your sisters, especially, since she doesn't seem to know immigration stuff well, all hearsay......
On this board I found the most inappropriate advises came from familymembers or welldoers. Sorry to say that.
Idea might be to talk to a immigration lawyer, so at least you would exactly know what your options are.
good luck
