Hi ChrisMwn. Thanks for the response. Dad has below the normal blood platelet count. We compared the result of his medical report last 2011 with his latest full blood count and it improved to 25 counts only but still below the desired platelet count.
He had been issued by immigration a work visa 3 consecutive times after noting his medical condition but this is the reason why his application is delayed every time he renews his work visa.
His specialist report last 2011 said, "there is no medical treatment at the moment and he is fit and well to work."
He then forwarded this old specialist report to his CO to assist her with evaluating dad's medical history.
