If you have a question about a filing mailed to the Chicago, Dallas, or Phoenix Lockbox, e.g.:
- 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 LockboxSupport@uscis.dhs.gov 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.
But if your question relates to an application or petition that was filed online or mailed directly to a USCIS service center, or an application or petition that has already been accepted by the Lockbox, or if you have a question about your eligibility to file, you should instead call the USCIS Contact Center at (800) 375-5283, or contact the service center or office processing your case, via the email addresses below, or use the InfoPass system on our website, https://my.uscis.gov/appointment, to make an appointment at your local USCIS office.
USCIS Service Centers
The Service Center Operations Directorate (SCOPS) has five service centers (California, Nebraska, Texas, Vermont, and Potomac) that process and adjudicate certain immigration applications and petitions. Service centers do not provide in-person assistance with questions about your case.
If you have a question about your case, you may use our convenient online tools. If you have tried our tools and still need help, you may make an online case inquiry or reach out to the USCIS Contact Center. Depending on what information we need to respond to your request, the USCIS Contact Center may forward a service request to the service center that is processing your case. You will receive a tracking number, which you should keep for any future questions. We generally respond to service requests within 30 days (15 days for expedited requests). If you do not receive a response within 30 days (or 15 days for expedited requests), or you believe the response you received from the service center was incorrect, you may reach out to the USCIS Contact Center to have your inquiry elevated.
Visit the Feedback Opportunities page to find ways to engage with USCIS. You may also see a list of documents currently available for comment. If you would like to notify us of a systemic operational issue, such as a pattern of potentially incorrect notices, you may contact us at firstname.lastname@example.org.
For questions about Hague or non-Hague adoption cases, please call 877-424-8374, TTY (800) 877-8339 or send an e-mail: NBC.Adoptions@dhs.gov.
