you know that you can always switch to a part-time H1b to make more time, right? Also, apply to YC if you are interested and ready to commit, the visa thing is hard but not insurmountable (especially if you raise money). IIRC, The buxfers did it!

It's very easy to go down the road of, oh no there are so many obstacles, but if you're relentlessly resourceful, you can make it work :)
