  • You received a rejection notice and have questions about the reason your submission was rejected
  • You have a question about how or where to submit an application or petition that should be filed at one of the three Lockbox locations
  • You have filed more than 30 days ago and you have not yet received a receipt notice
  • You have other concerns or questions about a recent filing at one of the three Lockbox locations

In these situations, you may email us at  and we will answer each email in turn as soon as possible.  Please include the form number, receipt number, petitioner and/or applicant name, and mailing address with your email.  Please do not include social security numbers in emails.
