It can be frustrating that your petition's processing will take nearly 4 times longer when it would in another Service Center. However, the processing time does not matter in this case because the priority date for F2A category (spouses and children of permanent residents) now is June 1, 2010. This means that your wife will not receive her immigrant visa for another 20 months or, possibly, a bit longer. Her place in the queue is determined by the date of filing of the immigrant petition (the Priority Date marked on the Form I-797 receipt notice that you received from USCIS), not by the date of approval of the petition.
