What you are asking is suggestion for doing an Immigration fraud. :)
Transferring from any visa category to H1 is 100% legal / acceptable / Justifiable but entering US under some other visa category (with intention to change the status. i.e. knowing what you will be doing after 1 month) means while you will face Immigration office @ POE technically speaking it will be hiding / lying to Immigration office.
I know many people who have done it in past and still are doing but it has harm us (Indians) in a -ve way. (It has result in lost of Trust for Indians)
I really do not understand, why we are are so selfish that knowing what we are doing is wrong (morally) and will affect our own country men in future still don't hesitate do it.
I really hope and wish that all who entered in US on some other visa category (Especially L1, L2 and H4) and got H1 approved via some consultancy, USICS will start a project to identify these people (no matter even if they are holding GC now)and start deporting them so that remaining honest (Indians) do not have to suffer for what these few people have done in past.
