As others have said, Elite Visa. An alternative is to get a job here. Dependent on who your employer is you could get an extension of stay which would allow you to stay for several years before you/your employer needs to renew.
Might want to get your extension before 29th as that's a Saturday and immigration might not be open.
As to whether you can switch, it's possible yes but it depends on your prospective employer and immigration. Not all employers can meet the in country requirements as they're more onerous than applying out of country.
Nothing official yet no. If recent history is anything to go by then don't expect an official announcement until a day beforehand or even on the day itself.
