Additionally, USCIS is transferring some Form I-129 H-1B cap subject petitions from the Vermont Service Center to the California Service Center to balance the distribution of cap cases. If your case is transferred, you will receive notification in the mail. After receiving the notification, please send all future correspondence to the center processing your petition. If you are filing a Form I-907, Request for Premium Processing, to upgrade your Form I-129 H-1B petition to premium processing, send the completed Form I-907 with the appropriate fee to the center processing your petition.
