[neochan]

my cousins alberta pnp was already approved and he has already applied for PR last september of 2009.  His work visa and work permit will expire on April of 2010...
Questions:

1.  shall he tell his employer that he needs to extend his lmo and work permit?
2.  what are the possible scenarios that he might end up doing, please help...


thanks,
