If you have had a history of asthma you do not belong in the military, regardless of how many doctors sign a waiver. As part of standard basic training in all services you will be required to enter a building with CS, remove your mask, and inhale. If you have a history of asthma you may die from this exposure. In combat areas CS gas is routinely dispersed to disperse crowds. If you have a stateside assignment this will not matter, but if there is an overseas deployment, these is a probability you might be so exposed. There are good reasons for these restrictions.
Hello usaf_manny,
Just finished reading your comments. Here is what I would suggest.
I would make an appointment with your family doctor. I would tell your doctor that you would like to join the US air force. That you stopped using your asthma inhaler since you were 13 or 14. That you know you can't join the USAF if you have asthma. I am willing to bet that your doctor will suggest that you be given an asthma test. That will help you establish whether or not you still have asthma. Based on your comments, probably not, but the asthma test will make it official. Also your doctor can write a letter to the US air force stating the results of the asthma test. I wish you luck. Eve
