If you try to reunify your parents to go to Canada ,you need submit your information .The most important information is include your income and tax for three years period .

Of course,if you have a professional job, your condition is easier to conform the requirement. If your application is refused,you can file an appeal with the IRB within 30 day.But you must provide sufficient evidence to prove that your condition is satisfactory.First ,you must determine your financial is qualified.My opinion is economic condition that is the important factor.
