Different rules for different consulates, nightmares obtaining Numero de Utente, exchanging Drivers License (IMT probably the worst), Finanças and SEF probably the best and still challenging at times. Whatever the rules are, publish them in a straightforward, checklist type manner and get all the Governmental Agencies some customer service training. Answer all emails within 3 business days, answer your phone, simple things will go a long way.
