H1b transfer after the petition is revoked

Hello! My employer has withdrawn my H1B petition while I was outside US for vacation. Can I use the receipt number of revoked petition to apply with new company? Can I apply now or wait till April next year? I am overseas now. My H1B visa is expiring in a month.

you just need to find a new employer and file for H1B cap exempt transfer. Once approved you need to get your visa stamped ( as it is expiring in 1 month)

no need to wait till april
