Hello, I have applied for my parents' super visa, my father as a primary applicant. My mother got approval, but my father is asked to do Sputum Test, I believe due to TB symptoms. My questions are: 1) I am planning to do Sputum Test in private lab before going to affiliated hospitals, If he is diagnosed with TB and need TB treatment which I believe takes around 6 months, does he have to apply for super visa again after 6 months or just have to go for medical again? 2) If i withdraw his current application and apply for visitor visa, would it be OK? or will it affect anything due to their record with TB?
