Hey
I'm Saudi Arabian girl , I'll come to Canada to studying ESL at Brock University.
My brother  ((  24 Years Old )) i need him  to come with me he will stay 3 months only as Tourism , but the problem is
He is Unemployed now !!!

How we can get a Temporary residence visa for him without Job letter or student letter... ?  *cry*

Is there any chance to refuse his application if my sister's husband became a Finical Support for him?

he's working as Computer Engineering he gets 3,800 $ per/month.

Is it okay when he being finical supporter for my brother who's unemployed to extract the TR Visa for 3 months..

Is it Ok ALSO, when we have the same finical supporter  *??*

Please help .. i Need help before my future go on.

Thank you All ,hope To hearing from Anyone  ,
