The waiting period for adjudication of an I-130 Immediate Relative (Parent) Petition depends upon the USCIS backlog of immigrant visa cases at any given point in time, but, on average, from 5 to 7 months from date of receipt of the I-797 Receipt Notice. The delay is not in the availability of immigrant visas for the Immediate Relative parent since there is no quota for such IR's, but rather depends on the number of such cases still in process at the USCIS Service Center handling the particular case.
