I am going to studying for a full time masters course starts this year Oct.
Does anyone know: if I apply and obtain my student visa before Oct, will my PSW be invalid? - Would I still be able to continue my current job if I get my student visa?

If not, what are you suggestions? To resign 1 month before term starts and apply for visa? I'm a bit sceptical about HomeOffice's processing speed tbh...
Many thanks!
