U.S. Citizenship and Immigration Services (USCIS) applicants and petitioners may need help checking a case status, understanding processing times, replacing a missing notice or card, changing an address, requesting an appointment, accessing a USCIS online account, asking about a delayed case, or reporting a possible immigration scam.

USCIS provides automated telephone information, live Contact Center assistance, online case-status tools, secure messaging, e-Request services, appointment requests, and specialized support for certain immigration programs.

How to Check USCIS Case Status

USCIS provides Case Status Online for applicants and petitioners who have a receipt number.

A USCIS receipt number is generally a 13-character identifier consisting of three letters followed by 10 numbers.

To check a case:

Locate the USCIS receipt notice.
Find the receipt number.
Open the official USCIS Case Status Online page.
Enter the receipt number without dashes.
Review the most recent case action or status.

USCIS states that its online case-status page generally provides the same basic status information that a Contact Center representative can see, so checking online first can avoid an unnecessary telephone call.

A USCIS online account can also provide case history, notices, secure messages, and other services for eligible cases.

USCIS Processing Times

USCIS processing times vary by:

Form
Form category
Field office or processing operation
Workload
Staffing
Requests for evidence
Policy or operational changes
Facts of the individual case

Use the official processing-time tool rather than relying on another applicant’s timeline.

USCIS currently explains that the processing time shown for many forms reflects how long it took the agency to complete 80% of recently adjudicated cases.

A displayed processing time is not a guarantee that an individual case will be decided within that exact period.

When Can You Ask USCIS About a Delayed Case?

USCIS does not allow a normal “outside processing time” inquiry for every pending case immediately.

Use the Processing Times tool and enter the applicable case information. USCIS will indicate whether:

The case remains within normal processing time, or
The case has reached the point where an inquiry can be submitted.

If the case qualifies, use the USCIS e-Request system or another support route shown by USCIS.

Opening repeated requests before a case qualifies generally does not cause it to be processed faster.

USCIS e-Request Help

USCIS provides e-Request services for several common problems.

Current options include:

Case taking longer than expected
Notice not received by mail
Card not received by mail
Document not received by mail
Appointment accommodation requests
Typographic errors on certain notices or documents

Before submitting a request, gather:

USCIS receipt number
Form number
Filing date
A-Number when applicable
Applicant or petitioner information
Email address

Keep the service-request confirmation after submitting an inquiry.

USCIS Contact Center Calls and Callbacks

Live USCIS Contact Center representatives are generally available Monday through Friday from 8:00 AM to 8:00 PM Eastern Time, except federal holidays.

If additional assistance is required, the inquiry may be escalated.

USCIS states that an escalated callback may occur between:
7:00 AM and 8:00 PM ET, Monday through Saturday.

If you recently requested USCIS assistance, be aware that a legitimate USCIS callback can occur outside the ordinary weekday live-agent hours.

However, remain cautious about callers asking for money, passwords, financial information, or unusual payment methods.

Calling USCIS From Outside the United States

People outside the United States and U.S. territories can use:

212-620-3418

for the USCIS Contact Center.

International applicants should also determine whether their specific matter is handled by:

USCIS
A USCIS international field office
The U.S. Department of State
A U.S. embassy or consulate

A visa application processed by a U.S. embassy or consulate is not necessarily a USCIS customer-service matter.

USCIS Appointments

USCIS does not generally encourage people to visit field offices without an appointment.

Current online appointment requests are available for certain services including:

ADIT stamps
Emergency Advance Parole
Certain immigration judge grants
Other qualifying services

If the online tools do not offer the service you need, call the USCIS Contact Center.

USCIS appointments are free. Be suspicious of anyone attempting to sell a USCIS appointment.

USCIS Biometrics Appointments

Applicants who receive a biometrics appointment notice should follow the instructions on that notice.

The notice identifies:

Application Support Center
Date
Appointment time
Documents to bring

If the appointment needs to be rescheduled, use the current rescheduling instructions provided by USCIS rather than simply missing the appointment.

Failure to appear without properly rescheduling can affect a pending immigration benefit request.

USCIS Address Changes

USCIS strongly encourages eligible applicants to update their address through a USCIS online account.

Most non-U.S. citizens in the United States are legally required to report a change of address to USCIS within 10 days of moving. Exceptions apply to certain categories, including A and G visa holders and visa-waiver visitors.

Changing your mailing address with USPS does not change your address with USCIS.

USPS also may not forward USCIS documents.

If you move:

Update the address with USCIS.
Include applicable pending receipt numbers.
Update USPS separately when appropriate.
Save the USCIS confirmation.

Special address-change procedures apply to certain protected cases, including some VAWA, T, U, and abuse-waiver filings.

USCIS Online Account Help

USCIS provides online-account technical assistance for:

Password resets
Locked accounts
Two-step verification problems
Lost access to an authentication method
Online Access Codes
Account deletion
Other technical issues

Customers with eligible accounts can also send secure messages through their USCIS online-account inbox.

Do not include sensitive immigration or identity information in ordinary website-feedback emails.

How to Request USCIS Expedited Processing

USCIS considers expedite requests on a case-by-case basis.

Possible criteria can include:

Severe financial loss to a company or person
Emergency or urgent humanitarian circumstances
Qualifying nonprofit organization interests
Urgent government interests
Clear USCIS error

Meeting one of these categories does not guarantee approval.

USCIS generally expects supporting documentation, and the decision to expedite remains within USCIS discretion.

Different procedures apply to some immigration benefits, so review the official expedite instructions for the exact application or petition before making a request.

USCIS Military Help Line

USCIS provides a dedicated line for current military members, eligible family members, and veterans:

1-877-247-4645
877-CIS-4MIL

USCIS currently lists military help-line representatives as available Monday-Friday from 8:00 AM to 6:00 PM ET, excluding federal holidays.

The line can assist with matters including:

Military naturalization cases
Address or duty-station changes
Certain expedited military cases
Posthumous citizenship information

Does USCIS Give Legal Advice?

USCIS provides information about immigration forms, procedures, case status, filing requirements, and agency policies.

USCIS Customer Service does not act as an applicant’s attorney or provide personalized legal representation.

If you need legal advice about:

Eligibility for an immigration benefit
Removal or deportation proceedings
Criminal history
Prior immigration violations
Waivers
Appeals
Complex admissibility issues

consider speaking with a licensed immigration attorney or an accredited representative working for a Department of Justice-recognized organization.

USCIS warns that a “notario público” is not automatically authorized to provide U.S. immigration legal services.

USCIS Scam Warning

USCIS issued a fraud alert in June 2026 after receiving reports of scammers making unsolicited calls while impersonating USCIS or other immigration-related organizations.

Scammers may:

Ask about immigration status or a pending case
Demand personal information
Request financial information
Spoof a government telephone number on caller ID
Threaten arrest, deportation, or case cancellation
Demand immediate payment

If an unexpected caller claims to be USCIS and pressures you for information or payment, hang up and verify the matter directly through USCIS.gov or the official Contact Center.

How USCIS Accepts Fees

USCIS warns that it will never ask you to send immigration fees to an individual by telephone or email.

USCIS does not accept immigration-fee payments through:

Gift cards
Western Union
MoneyGram
PayPal
Venmo
Cryptocurrency sent to an individual

Some immigration fees can be paid online through an official USCIS account or Pay.gov when USCIS instructions authorize that payment method.

Always confirm the current fee and payment instructions on the official form page before filing.

USCIS Forms Are Free

USCIS immigration forms can be downloaded for free from USCIS.gov.

Be cautious of websites that:

Charge simply to download a USCIS form
Imitate a government website
Claim to guarantee approval
Promise unusually fast processing for an unofficial payment
Use a domain designed to look like USCIS.gov

Official federal government websites use a .gov domain.

Fees may still apply when filing a particular immigration benefit request, even though the blank government form itself is free.

USCIS Headquarters

USCIS headquarters is located in Camp Springs, Maryland.

U.S. Citizenship and Immigration Services
5900 Capital Gateway Drive
Camp Springs, MD 20588

USCIS is a component of the U.S. Department of Homeland Security.

This headquarters location should not be used as a general mailing address for immigration applications.

Each form has specific filing instructions. Depending on the case, a filing may need to go to a USCIS Lockbox, service center, field office, or another designated location.

Always use the current “Where to File” instructions for the exact USCIS form.

USCIS Versus the State Department, CBP and ICE

Different federal agencies handle different parts of the immigration system.

USCIS generally handles immigration benefit applications and petitions such as:

Green Cards and adjustment of status
Naturalization
Employment authorization
Family and employment petitions
Certain humanitarian benefits

U.S. Department of State handles many visa and consular matters outside the United States.

U.S. Customs and Border Protection (CBP) handles inspection and admission at U.S. ports of entry and certain border-related matters.

U.S. Immigration and Customs Enforcement (ICE) has separate responsibilities involving immigration enforcement and related matters.

Contacting USCIS about a case controlled by another agency may not resolve the issue.

How to Escalate a USCIS Case Inquiry

If an ordinary case-status check does not resolve your question:

Check Case Status Online.
Review the current processing time for the form and processing location.

Determine whether the case is eligible for an inquiry.
Submit an e-Request or secure message when available.
Call 1-800-375-5283 if further assistance is necessary.
Keep the service-request number and any USCIS response.
If USCIS escalates the request, watch for a callback during the agency’s published callback hours.

An escalation or service request does not guarantee approval of an immigration benefit or faster adjudication.
