Hello everyone, Kindly advice on this issue please.

My Tier4 visa is expiring before month end, I have an offer already but it seems the employer is very slow with processing. Currently, I am thinking of applying for the PSW visa, can I still apply for the PSW visa a week to my visa expiry date?

Read on gov.uk that I can apply before my visa ends but I want to confirm and be certain.

Thank you.
