The worst . My company has been using them to get my H1b for two years. They literally didn't do anything except collecting money. First year, they never contact me about the status although I didn't get the lottery. Second year, I got the lottery and RFE, because they didn't do anything so my case was rejected. If you really need to choose them, make sure to follow up. I guess i trusted them too much. Then funny thing is, they are asking me to get them do another year LOL.
