It is noted from a colleague of mine who had applied along with me for Canada had received his medical for him and his wife.Wife being a co applicant had found a scar in chest xray.They had noted a abnormal comment in teh medical form and send to london.Infact she had done a skin test for TB and the result was 10-12mm.Is there a chance for the Immigration officer to reject the application of both husband and wife or give visa only for husband who has a clear health history and to reject the co-applicant.Infact skin test reading shows that she is not affected by TB.Seniros please advise
