My father is on a work permit that is going to expire September 2009. My brother (17) is applying for a VISA now and our family is really PRAYING that nothing untoward happens in the application process.

My question is, should my father's company extend his contract and apply an extended work permit for him, will my father still be able to claim my brother as a dependant, who by September 2009 will already have turned 18?
