H-1B Cap exempted / H-1B extension based on previous employer's I-140 approval

[laskan2k]

a) Is a cap exempted h-1b possible with the I-140 approved with one of the previous employers?

b) Is h-1b extension possible with the I-140 approved with one of the previous employers?

kindly clarify these queries.

An I-140 approved with a prior employer can be used for a 3-year H-1B extension with a new employer as long as it has not been withdrawn/revoked and as long as the priority date is not current.

Thanks.

Could you please let me know if a cap exempted H-1B petition is possible?

As i understand that I-140 can be withdrawn/revoked only if the employee has committed any fraud. Am i right?

Is there anyway an employer can withdraw/revoke I-140?

What if I-140 is revoked/withdrawn without the employee committing any fraud?

Thanks Again
