USCIS announced on May 15th, 2018 that they have completed Data entry for all the petitions that were selected in H1B Visa 2019 Lottery.
USCIS said that they will start returning the petitions that were not selected in H1B Visa lottery soon, but did not give any timeline for the sam as the volume of petitions is large. Based on previous data we can expect to have the returning of these unselected or rejected packages to arrive in mid July or so.
USCIS also will transfer some cases around between two of the Service Centers Vermont and California to balance the load
USCIS also said that employers or attorney should not reach out to them until they either get a H1B receipt notice or a rejected package. To make it easy, USCIS will release a press alert indicating that they have returned all rejected petitions and then employers can plan to contact USCIS based on that.
Overall, the key info is that you can expect to receive H1B receipts soon and rejected packages as well…so stay tuned !
