My now wife and I used rapid visa last year to assist us in preparing her fiance visa. In addition to havnig one of the simplest forms to fill in, the people behind rapid visa were able to answer a host of questions that arose as we went through the process. We had run in to a variety of snags and slow downs which the rapid visa were able to explain and assure us that things would work out which they did.
I would recommend them to anyone seeking an easy way to fill out the forms.
