If I have a disability, can I automatically receive services?

 No, VESID is not an entitlement program. In order to receive services, you must be determined eligible. This requires that you provide VESID with documentation about all of the following:
„h that you have a medically diagnosed physical, developmental, or emotional disability;
„h that your condition(s) creates significant impediments to your ability to work;
„h that there is a reasonable expectation that VESID services will enable you to work; and
„h VESID services are required to enable you to become employed.
Whether or not you receive benefits (SSI or SSDI), you may still be eligible to receive services.
NOTE: Individuals who are legally blind are served by a separate agency, the New York State Commission for the Blind and Visually Impaired.
