Do I need to reply iccrc to update them that asked tests has been done or there is no such requirement?
my father has heart problem but it is stable for four years. he had to do aditional tests as well.
In your father's case, They always ask for additional tests for any person who had TB once in life. So you should't be worried. I have heard that TB leaves mark on chest X-ray for whole life.With additional tests, IRCC is going to make sure he doesnt have that problem anymore. it may take some time but your father will get visa soon.
