I'm getting ready for a medical exam for my visa and I'm really worried because I'm a smoker. I usually go through about two to three packs a day, but after hearing about the x-ray exam, I got pretty anxious and decided I need to quit. The cravings have been intense, so I'm down to a maximum of five a day for now. Im wondering, do these changes or any lung patches I have increase the chances of my visa being rejected? I could use some advice.
