The USCIS is reasonably reliable about issuing an EAD within 60-90 days of filing the application. If by the time of a successful adjustment of status interview you still have not received an EAD, the Atlanta Field Office should be expected to cooperate in placing a stamp in your passport that immediately can be used to show your new status, including authorization for employment and travel. Additionally, an immigration attorney who is familiar with your case may be able to advise about other steps, such as an INFOPASS appointment or liaison inquiry, that may be helpful in your specific circumstances to obtain evidence of employment authorization without having to wait until approval of an adjustment of status application.
