Can I switch from PSW to another category

Hello,
I am writing on behalf of my friend.
He is here on a Post study work visa which is expiring next year.

Is there any visa he can switch to?

Does he need to have a job to move to another visa category?

Will be require the company to sponsor him for any other type of visa?

Your advise would be very helpful.

Thanks

e can switch to tier1, tier2 or tier4 visa

Thanks for the response.

To switch to Tier 1 does he need to have a job?

He cannot switch into Tier 1 General, Tier 1 General has closed to all new applicants including those on Tier 1 Post-Study.

Tier 1 Investor and Entrepreneur are available.

He is able to switch into Tier 2 for which he will need a job and sponsor. Or switch into Tier 4 Student.

Many thanks for your response.
