According to current August 2013 visa bulletin, petitions by green card holders for minor children in the F2A category is current across the board including for citizens of Philippines. This means, if you file a petition for your son now, a visa is going to be immediately available. And I suggest you do so right away. To be sure your petition is correctly prepared and so as to avoid delays, I suggest you hire an immigration lawyer. because, the priority date may regress, (become unavailable) again.
