Yes, the USCIS has provided not only a unique mailing address for its Premium Processing customers, but it has also established a special phone number and e-mail address for each of the Service Centers. These special communication channels will be used solely by Premium Processing customers.
The USCIS also collects, on the Form I-907, your phone number, fax number and e-mail address so that they may correspond with you in the most appropriate manner. Premium Processing customers should be prepared to receive information on their case through any of these three types of communication.
In addition, the USCIS allows I-539 applications for dependents to receive the same expeditious processing as the principal family member’s I-129 petition, at no additional cost if they are filed at the same time.
