I have been in with a NZ and British passport when one or the other was nearly full, no problems and no questions! The last time being 3 years ago, so things may have changed since then!
If you have money to burn! Get an agent! Otherwise go yourself, early Morning start advised, and enjoy the experience! Reception will give you all the forms you require or can go downstairs to the shopping center where you will find several photocopy shops, and all the required forms, and they are well versed in the requirements required! Good luck and enjoy!
