Just to give an update on my experience doing EOA at MIA. Arrived at terminal D international arrivals at approx. 10 am. Went to the APC machine and completed the immigration process with my printed receipt. I proceeded immediately to the Global Entry line where I informed the officer I was doing EOA. He made me wait on the side before an officer came to take me to secondary screening. I waited approx 10 minutes before seeing an officer where I was asked simple questions and prints were taken. Whole process took about 20 minutes.
