This is not true. They are not going to issue them with the VISA until a TEST is Negative.
The reason for this is:
Tuberculosis (abbreviated as TB for tubercle bacillus or Tuberculosis) is a common and often deadly infectious disease caused by mycobacteria, in humans mainly Mycobacterium tuberculosis . Tuberculosis usually attacks the lungs (as pulmonary TB) but can also affect the central nervous system, the lymphatic system, the circulatory system, the genitourinary system, the gastrointestinal system, bones, joints, and even the skin.
Tuberculosis is spread through the air, when people who have the disease cough, sneeze, or spit.
One of the primary aims of Medicals is to safeguard the Canadian Population and the spread of diseases.
I am afraid they will have to wait until cleared.
Applicants must get treatment and then they'll have to be re-tested to ensure that the TB is gone for good.
