Are there any additional benefits to the program? Yes. USCIS has also established a special phone number and e-mail address for each of the Service Centers. These special communication channels will be available only to Premium Processing Service customers. Additionally, USCIS collects your phone number, fax number and e-mail address on the Form I-907 so that we can send you (the petitioner or attorney or representative) an automatic e-mail notifying you of the receipt of your Form I-907. If the underlying form for which you requested Premium Processing Service is approved, we will send an automatic e-mail notifying you of the approval. It is important that you provide this information so that USCIS may correspond with you in the most appropriate manner. In addition and at no additional cost, USCIS will strive to provide faster processing of Form I-539 applications filed by dependents of the principal beneficiary of a petition for which Premium Processing Service has been requested if the Form I-539 is filed at the same time. USCIS provides this service as a courtesy. Consequently, it cannot guarantee faster processing of the Form I-539. 从官网上截下来的有关PP的信息。。。
