I received a phone call two days before the ceremony telling me where to go, what time, and to wear formal clothing and I was allowed one guest. We arrived at 830 for a 900 am start. It takes place in the auditorium on the first floor of the Police and Immigration building which is about a five minute walk from Caribe tours. Once in the auditorium you line up and show your passport and they check your name and you sign in two places. Once everyone is in place itès national anthem, a short speech by the vice-minister, they read out the names and countries of those becoming citizens, then do a group oath. Next they call people alphabetically by first name. They present you with your certificate and all the paperwork to receive your cedula and passport. Once everyone has their certificate and photo taken it a group photo and the nation anthem again. Finally its snacks and juice/water and opportunity to congratulate each other and ask questions of the staff. Then you go your merry way, usually to the JCE to apply for your cedula- second floor, but make sure you get a photocopy of the entire set of the documents stapled together inside your folder. You get a number and wait your turn. 1500 pesos and you wait 30 days for your cedula and if you want it next day you pay the extra for VIP service. If you elect the 30 day service you don't have to go back to Santo Domingo, you can do it in your local JCE. You also receive an envelope that you take to get your Dominican passport. You are told that you are not allowed to open this envelope. That's about it.
