Global VIP is fine as long as you don't listen to any "advice" they give. Almariel was told the wrong thing but double-checked her info on UKY, stuck to her guns, and got her visa. Frankly, I think the same caveat should be applied to all expediters who aren't also immigration lawyers, which is most of them. They're great for getting your visa processed quickly, just remember they're not advisers or experts. That's all.
