As permanent resident, petitions for minor children (under 21 yrs) or spouse is in the 2d preference family category, F2A Current projection for visa availability in that category is about 25 months. If you filed an I-130 petition in Apr. 2012, I'd speculate that a visa will become current within the next 19 months or so. You should have received Form I-797C Notice of Action from CIS usually within 2-4 weeks of mailing your I-130. That notice is both the receipt for the fees paid; CIS' acknowledgement of receipt of your petition and the priority date. If you have not received any correspondence at all since Apr. 2012 from CIS, it is doubtful that they received your petition or even that you have a case pending. You should therefore make an inquiry as soon as possible. Given the long wait times for petitions, you need to be sure of things so that you are sure your wait is not for nothing.
