Guess you have not been keeping up to date either.
You will see a change in hiring practices for next year. Apparently HK immigration approved work visas for the latest grad expat cadets, however indicated that there will be no future work visas for icadets as there were several formal complaints from HK locals filed lobbying that the cadet program was designed for locals to promote aviation careers for locals.
Taken from another thread. May be true may not, CX can probably buy their way out of it somehow though. Lets see if any more cadet courses with expats start in the near future for an indication of how seriously the company are taking it.
