it's to early to say if the general quota or some NOC quota has bee reach.
there were few fake accounts that was saying that every application after september will be return...then all from around 20 Oct
everybody saying smt different but there are no any official info.
don't panic for few more days. Now CIC giving AOR for people from middle Sept so you have time....
but you can of course start filling EE account just in case (I did it...)
