Her present visa probably only expires in 2013 so there are no problems on that account. You haven't directly answered my question but from what you say it appears that she hasn't yet been contacted by UKBA about the curtailment of her leave.
The 60 days count from the date of UKBA's decision, not from the date she left her previous employment, so if UKBA haven't taken the decision yet (because they are busy, etc. etc....) she will have at least 60 days from now.
Sponsor licence applications currently take 2-4 months to process
When she gets the notice of curtailment, and approx. 4 weeks before her curtailed visa expires, she should ask her prospecticve employer to send an email to UKBA to the following two addresses explaining the circumstances and requesting urgent treatment of the application.
sponsorlicensing.support@ukba.gsi.gov.uk
scoc@ukba.gsi.gov.uk
The prospective employer can also make enquirires about the progress of their application to 0300 123 4699.
Has the prospective employer already done the resident labour market test for her job (takes 28 days)?
If in the end she has to leave because she doesn't have a CoS at the time her visa expires then unfortunatekly the 12 month coolig-off period will apply to her.
