1-94 expired but H-1B renewal still pending

[roisin]

Hi (first time posting)

My 1-94 is due to expire at the end of the month and my H-1B renewal is still pending (with USCIS since June 11th and will prob not be ready till August 11th). Does anyone know if I need to leave the country on the date that my 1-94 will expire? Is it ok to stay in the US until the paperwork is through? If the paperwork is still not through when I leave the US on August 13th to attend a family event I would have to hand in the expired 1-94 - would this come against me in the future when I apply for a green card?
Thanks very much

Thanks so much as I was really worried that I was jeopordizing any future green card application by remaining in the US on an expired 1-94
