The average processing time of a Form I-130 petition by a legal resident for a spouse or child under the F2A category is currently about 4 months as shown in the Dec 2013 visa bulletin. This means that an F2A petition that is now current was filed on or before Sep. 8, 2013. If CIS received your own petition Nov. 23, 2013, and, assuming the current projection holds, your I-130 approval and priority date will be sometime in Feb 2014. Note these are mere projections that may or not hold true come Feb. 2014. Also it does not include cases where CIS requests additional evidence or other unforeseen delays. Check the USCIS web site regularly for status of your petition.
