Expired passports? All DFA offices are fully booked? Here's some tips to get your earliest schedule or appointment. 1. Search the nearest DFA site, avoid biggest sites or the sites that is very popular. 2. If the site you have chosen is fully booked, wait for another hour. Every hour, the DFA website updates their schedule. For example, you check the website at 8:25, refresh the website at 8:59. Make sure that you have a stable and fast internet service. It is best to search schedule every midnight or between 12mn till 5AM.
