Qualified Veterans need to provide a copy of their Certificate of Release or Discharge from Active Duty form, known as a DD214.
The state of Pennsylvania reports that the easiest and fastest way to get a Work Opportunity Tax Credit (WOTC) Certification for your Veteran applications is obtaining a DD214. The easiest way to receive a DD214 for all your Veteran applications is to request it from the National Archives website. This process may take a few weeks.
