I was asked to leave UAE because of the scar in my lungs x-ray which indicates old TB even if I don't have active TB. I want to get it cured and go back to Dubai with medication proof. Can you please suggest a way and that have you dealt with any such case in the past as the only purpose of the treatment is to go back to Dubai and it has to be legal.

Its important to consult a pulmonologist for proper evaluation and treatment of the old TB scar. They may recommend a course of medication to ensure there is no active infection, and you can get documented proof for immigration purposes. I havent directly dealt with such cases, but many patients go through this process with proper medical support.
