I am waiting for medical call from visa office. I heard that during medical check up they do X-ray and blood analysis.
I my case my wife is pregnant and during this period as far as i know X-ray is dangerous for her health and baby. So, what is the alternative for this situation?
If you receive the medical forms from CIC while your wife is pregnant, hold them with you and send a letter to your visa office explaining the situation and they will give you an extra time until your wife gives her birth.
That is normal situation and i have seen many similar cases to your case in this forum who were given more time by CICs until they got birthed.
