At last, after months of waiting, I finally got my new passport! Getting a passport appointment from the DFA website was a long wait. I was waiting for a slot since September to renew my passport, but the schedule was full until December! I made it a habit to check the website for a slot, but there was no luck, every time, not until I saw a post from an FB group which I am member of. In that post, it says that there is a site where you can access the DFA real time calendar.
