My lung scarring was first found out almost four years ago when i had my pre employment medical exam here in the Philippines. And eventhough the sputum exams all came out negative and i didnt have any symptoms, i was still required to undergo treatment and after was given a medical clearance to continue working. And now i already have my H1B visa but came up with a problem because of the pleural thickening found in my chest xray. And eventhough i submitted a medical clearance from my doctor the agent handling my papers told me that there is only a slim chance that i can still have the job despite already having the visa. Pls pls help! Anyone have similar situations or have answers?
