Notifying employer about changing from tier-2 to tier-1

[orphean]

Hi,

I work in a bank and on a tier-2 ict visa. I will be changing my visa to a tier-1 visa next month.

Do I need to notify my HR department before I apply for my visa? Or should I change my visa status, re-enter the country over the weekend and then notify my employer?

Does all my employer need is the proof of right to work, in this case, the tier-1 visa?

You can change your visa status and then inform your employer. Also reassure your employer that you do not intend to move on and you are committed to stay with them.
