I will be shortly applying for my wife's spies visa, with what should be a quite straight forward application. I would however not like to deal with the stress of completing and submitting the applications. I'm thus looking at getting some help from an agency or immigration lawyer. I've received quotes for up to £2.500 for this service (excluding UKBA fees). I have never seen the application forms. Are they difficult to complete? Is it worth getting an agency on board? Has anybody had any good experience with any agencies?
