New Stevens.. trainee....

First of all, call Stevens and speak to the doctor's office. They are the ones that make the decision.
I have not seen Stevens disqualify anyone for BMI issues. Lot's of rumors, but no facts.
If you are required to have a Sleep Apnea test, you will be put on medical hold until the test is completed and accepted.
You are not disqualified for SA. you may be required to use a C Pap machine. There are quite a few drivers with Stevens with C Pap machines.
Speak to the medical department directly and get a straight answer.
