Is it feasible for someone w/ a student visa to get working visa in the future?

Thanks Leon.  So she should just keep mum about her having a sister in Canada.  Won't the subject of her having a relative be brought up though during the interview and in the application itself?

If it does come up, then tell the truth. But if they don't ask, then don't tell. You need not volunteer information.

Having a sister there may work against her as immigration might be inclined to think that she has come to re-unite with her sister and will not be leaving at the end of her studies. 

That is scare mongering. Having brothers or sisters in canada donot entitle an immigration officer to reject your application. You must always be truthful and straight forward. Each application is decided upon its merits. Canadian immigration or CIC officers are smart and well trained individuals and can digout what they want to. Donot withhold any information and declare what you have to declare. Making false statement or witholding information can jeapordise your application.

Its better not to learn tricks that can make you face hard time! good luck.

Be careful there! Under several legal systems - and I believe Canada is no exception - no one is forced to produce evidence against him/herself. this basically means, if you have not been asked, then you need not tell (notable exception: if you're coming to canada with more than $10,000, you must let them know).

Yes answer what is asked. Declare what is legally required to be declared. But donot depend upon tricky tricks!
