New Zealand Nanny visa extension/reapply??

[themaleworrier]

We have the most wonderful nanny from NZ who is in the UK on a Tier 5 Youth Mobility Visa due to expire in April 2013. I know that this type of visa can't be extended but can she leave the country and reapply for another type of visa and then (hopefully) return??

An Extension is Not Permitted.
Reapplying is Not Permitted
"If you have previously spent time in the UK under the YMS or under the Working Holidaymaker Scheme you are not eligible to apply under the YMS."
(Source YMSGuidance(pdf))

So it can't be the same type of visa, it needs to be something different - but what?

Maybe she will meet the man of her dreams at a christmas party and marry him before April?

thanks nannynick; she has a boyfriend but the rules say you cannot get residency if you marry within six months of the visa expiry!
