@smack, from what I understand you applied for study, got rejected, then applied for family (it is in process as we speak) and now you want to apply for visitor visa.
no idea if anyone can tell you what the chances are, if you have money to spend more and nerves to make another file for visitor visa, you can try it! i sent the files via courier in 17 and in 26 i got the passport home, so they answer quite fast.
if i were you, yes i would apply for visitor visa too, and i would say that i applied for school but got rejected, now i only want to go and visit because PR takes too much and I miss my partner. they can reject you (hopefully not!), but at least you have tried! please consider that i don't have ties to home other than my self employed firm with good income.. so maybe they are not so mean.
