It depends.  In OWI -1st situations, the client is immediately eligible for an occupational license.  However, this assumes that the client had no prior revocations or suspensions within the one year period prior to the new revocation.  If there is a prior revocation or suspension within one year, the client will be ineligible for an occupational license. 

If a client's license is administratively suspended, the client is also immediately eligible for an occupational license. 

In OWI-2nd cases, there is a 60 day waiting period for the occupational license.  However, this waiting period would be increased to one year if there is a prior OWI related conviction within 5 years of the new violation.  The five year period is calculated by looking at violation dates.  If the prior violation is outside of the five year window, then the 60 day wait would apply.  Once again, this assumes that there are no prior revocations or suspensions within the last year.

In an OWI-3rd or subsequent case, the wait is 90 days.  However, once again, the length of the wait can be longer (one year) if there was a prior OWI within five years of the current violation.  However, the wait would also be one year if there are any two prior violations within five years of each other. Thus, if the priors were in 1993 and 1997, and the new violation was in 2009, there still would be a one year wait because the 1993 and 1997 violations are within 5 years of each other. 

Once again, if there was a prior revocation or suspension within the last year, you might also be ineligible for an occupational license.

In refusal situations, the wait for the occupational license is longer.  If the refusal is considered a first offense, the wait is 30 days (assuming no other revocations or suspensions within the last year).  If the refusal is considered a second then the wait is 90 days.  If the refusal is considered a third offense, the wait is 120 days.  Again, this is assuming no other revocations or suspensions within the last year and that there are not two countable OWI related offenses within five years of each other.
