It is not clear what you are asking. There are two bulletins. The first indicates what priority dates may file a visa application. The second indicates what priority dates currently have a visa available. The two bulletins are designed to speed up the processing by more accurately predicting visa usage. The visa bulletin is updated monthly. You and your son should be contacted by the NVC when an immigrant visa will be available to him in the near future.
