I've just been selected in H-1B Cap lottery. Company sponsoring me is now going through all the paperwork, but the issue is: their business is not very stable, projects come and go (and recently mostly go). I wonder, if they will rescind the offer can I use the fact that I was selected in lottery to get sponsored by another employer? Or do I have to get lucky in the lottery next year?
