Quoting 86ti from another thread:
My question is, has anyone been successful in obtaining the EEA FP without completing all the answers and providing all the extra documention they "require"?If you decide to apply for an EEA FP you will have to fill out form VAF5 but be warned that it asks for many questions that you do no have to answer. All you should need is documentation proving the relationships and the passports. Nothing else, especially you do not have to declare why you want to come to the UK, how long you want to stay or if you have sufficient financial resources to support yourself and the family. The stay for the first three months is unconditional (except your passports and maybe the EEA FP). After that time you must be able to support the whole family.
