Lung scar in medical

I have a friend who is coming from the Philippines thru agency. I hired him thru an employment agency in the Philippines.

Now here's the problem. on his medical examination IN THE PHILIPPINES his x-ray shows a scar on his lungs. but he do not have any disease nor any complications. it was from previous problems that had already been treated. to make the story short after getting a recommendation from a pulmonologist he was given a fit to work certification and his visa is now under process here in Qatar.

This is my question. do you think he will pass the medical examination here in Qatar? given his situation?

Anybody had this situation before?

Any suggestions on what to do?

Thanks. .
