What are the chances of someone's parents getting a visitor visa (father age 72 years and mother 62 years). Father has some health issues. Both parents own no property, have a minimal bank balance and are both retired with no source of income. They do have some children living in Pakistan where they are applying from. Father has no recent travel history and neither does the mother. They want to apply for a visitor visa to visit their married son in Canada. Their son earns a good salary (above 90 k /year). What are the chances that the parents will be able to get a visitors visa?
