I know at least two Y Combinator companies who moved to Valley. I believe YC helped the founders to get L1 visa.
If a US company or person is a partner in your company, then you may be able to get a L1 visa. I guess this can also work out if you have a US based investor, but I recommend to confirm from an attorney.
