i am 23 years unmarried son of legally permanent residence parents.how long does it take till i get immigration visa from the date of i-30 petition

Under the visa chart for November 2012, only those individuals who applied under the F-2B category for unmarried sons and daughters over the age of 21 of permanent residents before October 8, 2004 (for all born in countries of the world other than Mexico or the Philippines) can finalize their immigration to the States. Thus at this time, there is an 8 year backlog. Visa chart time, however, does not equal real time, and so the actual time of waiting could be longer or shorter dependent upon the number of people applying and whether the allotted number of visas is increased, remains the same or is decreased by Congress.
