I am a physician working shift schedule. Unfortunatelly, my biometric appointment was scheduled during my shift day again ( the tird time). Despite my multiple requests to schedule during weeks when I am off, it is not happening. I do not want abandon my patients since thee is no other physician available that day. I tried to reach Philadelphia USCIS office on 103000 Drummond Rd directly, but was not lucky. I am wondering if there is such thing as “Walk in”. For example, If I come a few days earlier than my existing appointment, will they let me in? It is approximately 5 -6 h drive for me to get there. So, I do not want to do it unless there is a chance to be seen that day. Any experience anyone?
