Parents New Residency visa for cured TB

Hi Guys

i am currently thinking of moving over to Dubai in next 3 years and would like to bring my parents with me as i am the only child. My mother was diagnosed with TB about 8 years ago and have been completely cured but does have the scar which shows in the xray.

She had made several trips abroad with no issues. She just had to do further tests which always came out as NEGATIVE. But i am not too sure how the medicals work in UAE.

Would her visa get rejected for a new residency visa in Dubai even if i furnish further reports from doctors as proof of NEGATIVE TB. Is this accepted?

Do all the places in UAE follow the same medical rules. I am really concerned on this

Can someone please explain.

regards
