I have seen a post where you have mentioned about COS for H4 to H1B. Im on H1B and i plan to bring my wife to US and go for COS in the April 2014 cap. Can you please tell me any consultancy where I can get this done and please suggest what all I need to keep in mind choosing a proper consultant. Any other suggestions are really welcome.
