i dont know exactly which consultant u r talking about but in general, people do go to consultants for such help ad they generally do it well.. but then it does vary from place to place...
Now are there any strong pointers on how I could make arrangements for funda? There is this consultancy in Chennai which claims it can make arrangement for funds with the relevant bank statements for a substantial fee. Are such people trustworthy? Do things like this really work in first getting the I-20 and then securing the Visa itself..
