如果485被拒,6年後的H1也立即會拒
You lose ground for the next H1 extension beyond 6th year because I485 denial. But your unexpired H1 time is still good. For most denial cases due to I140 denial, you can appeal I-140 and become eligible to request H1 extension again. If I485 denial due to inadmissiblity, then you are not welcome in US anyway, unless you can get a waiver.
