Same here. Requested an ADIT appointment last week and, surprise surprise, I missed both calls today. Totally my fault. Does anyone know what I should do in this case? They said on the email they sent when I requested the appointment that they would try twice before closing my request, so am I just waiting for an email saying the case was closed and then should request another appointment? This is very stressful for me as I am changing jobs and have international travel in April and need proof of status for both.
