Sponsoring H1B Visa with a new entity
We usually do not provide any advise related to immigration law, however I will attempt to answer your question:
As far as I know only established businesses with minimum number of employees and with physical offices in the US can sponsor H1B employees. This would have been too easy of a loophole if new entities without any real business in the US could sponsor H1B employees.
I would recommend you to consult an immigration attorney for further advise in that field.
