Non Resident Alien

Hi I am an Entrepreneur from India and have set up a 2 member LLC in Delaware.

We occasionally visit the U.S for business purposes and we have not really started our business

as our software is still in the development phase. So there is no money that we earned or spent in the USA. Ours is a LLC partnership entity. We don't have any employees or any expenses that we want to claim. Both of us have ITIN's. I would like to know if we have to file any return whether from the LLC's end or in our Individual capacity when there is absolutely no income nor expenses.
