An invaluable factsheet on the rights for disabled job applicants and the ADA:


http://www.eeoc.gov/facts/jobapplicant.html


To quote the most pertinent passage:

'An applicant with a disability, like all other applicants, must be able to meet the employer's requirements for the job, such as education, training, employment experience, skills, or licenses. In addition, an applicant with a disability must be able to perform the "essential functions" of the job the fundamental duties either on her own or with the help of "reasonable accommodation." However, an employer does not have to provide a reasonable accommodation that will cause "undue hardship," which is significant difficulty or expense.'

In other words you must qualify for a job on equal footing with able-bodied applicants and be able to perform the essential duties.  The prospective employer is not obligated to make accomodations if it feels they are out of line and unreasonable and a great expense.

This is essential reading if you're looking for a job.
