The officer is required by law to immediately forward a copy of the completed notice of suspension or revocation form and any driver license taken into possession, with a sworn report to the DMV.  A pink copy is given to you.

The DMV automatically conducts an administrative review that includes an examination of the officer's report, the suspension or revocation order, and any test results. If the suspension or revocation is upheld during the administrative review.  If the review shows there is no basis for the suspension or revocation, the action will be set aside. You will be notified by the DMV in writing only if the suspension or revocation is set aside following the administrative review.

You have the right to request a hearing to contest the suspension or revocation from the DMV within 10 days of your stop or arrest.   This is the first deadline you face.  If you hire an attorney, they can and will request the DMV hearing for you and appear on your behalf at the hearing and fight to save your license.
