请问怎么才算被抽中了呢？

我收到公司系统里的recipt number. 然后 我查了一下status.但也没说什么中没中。就说了 On April 17, 2015, we received your Form I-129, Petition for a Nonimmigrant Worker, Receipt Number xxxxxxxxxx and emailed you a receipt notice. It is being processed at our California Service Center location. The notice describes how we will process your case. Please follow the instructions in the notice. If you move, go to egov.uscis.gov to give us your new mailing address.

这算中了吗？
