You dont need to use a visa attorney. You just need to use someone who knows their way around the paperwork and what the embassy is looking for. For E2, Lesley is as good as it gets though she can be a little overcautious. She is fairly cheap, I think I paid around £2500 plus disbursements. You cannot move any faster than the embassy do. I got mine in 6 weeks, I understand it is now taking three months. They are dione strictly on a first come first served basis. For L1. you would recommend a different consultant. It depends what visa you are going for,
