United States Citizenship and Immigration Services (USCIS) is the Department of Homeland Security agency that processes many U.S. immigration benefit applications and petitions, including naturalization and permanent residence matters. Its official website is uscis.gov. The right starting point depends on whether you need to apply, check a pending filing, respond to a notice or contact support.

If you already have a notice, identify its agency, form number and requested action first. A USCIS receipt, a consular visa case and an immigration court proceeding use different services.
What does USCIS do?
USCIS stands for U.S. Citizenship and Immigration Services. The USAGov agency directory describes its responsibility for immigration and naturalization applications and immigration-service policies. USCIS is part of DHS; it is a government agency, rather than a private immigration consultancy.
The agency’s official forms directory shows the range of requests it handles. Common examples include:
- Family immigration petitions: Form I-130 concerns a qualifying family relationship.
- Permanent residence: Form I-485 concerns adjustment to permanent resident status; eligibility depends on the applicable route and circumstances.
- Employment authorization: Form I-765 is an application for employment authorization in an eligible category.
- Naturalization: Form N-400 is the application for naturalization.
- Resident card tasks: Form I-90 concerns replacing a Permanent Resident Card, including applicable renewal requests.
These examples identify services, not a checklist everyone should file. A family petition, an application for permanent residence and a request for employment authorization have different purposes. Approval of one filing does not mean every related application has been approved.
For the earlier decision about which route fits your goal, use our U.S. immigration pathways guide. Our Green Card eligibility and application overview explains the distinction between obtaining permanent residence and later card-related tasks.
How to find the official USCIS website
Start with USCIS.gov or the USAGov directory above, then follow the link for your task. Read the actual hostname: an official USCIS page uses uscis.gov or a subdomain ending in .uscis.gov. A web address containing “USCIS” elsewhere is not enough to establish government ownership.
The Federal Trade Commission’s immigration-scam guidance warns that private sites may imitate government branding and charge for free forms. Independent explanatory articles can be useful, but they are separate from the government service where you file or check a case.
Choose the USCIS tool that matches your task
| Your task | Official starting point | Prepare first |
|---|---|---|
| Find a form or filing instructions | All Forms | Filing purpose, form number and category |
| Use an account or start an available online filing | USCIS online-account instructions | Your own email and account-access details |
| Check a pending application or petition | Case Status Online | The receipt number for that filing |
| Check a published processing estimate | Case Processing Times | Form, category and applicable office selection |
| Report a move | Change-of-address instructions | New address and each relevant pending receipt number |
| Resolve a notice, account or service problem | USCIS Contact Center | Exact problem, notice and any deadline |
Example: “I have moved and have two pending applications” is an address-update task. Checking both case statuses does not update either mailing address. “My notice requests evidence” is a response task; repeatedly refreshing a processing estimate does not answer the request.
For detailed tracking instructions, follow our USCIS case-status guide. For form and office selections and inquiry timing, use the separate USCIS processing-times guide. Status, an estimated waiting period and a decision notice answer different questions.
USCIS vs. ICE, CBP, the State Department and immigration courts
The DHS component directory lists USCIS, Immigration and Customs Enforcement and Customs and Border Protection separately. Their responsibilities differ, although immigration matters can involve more than one agency.
| Agency or service | Main task relevant to this guide | Practical distinction |
|---|---|---|
| USCIS — DHS | Immigration benefit applications, petitions and naturalization services | Use the USCIS reference for the individual filing |
| ICE — DHS | Immigration enforcement and investigations | A USCIS benefits tool is not a detention or enforcement case service |
| CBP — DHS | Border and port-of-entry functions | A benefits application does not replace entry inspection |
| Department of State | Consular visa processing and visa-status services | A consular visa application can have a separate case reference |
| EOIR — Department of Justice | Immigration court proceedings | Use court instructions and hearing notices for that proceeding |
Official references: USAGov’s ICE directory, CBP directory and consular visa-status guidance, plus EOIR’s case-information page.
For example, someone may have a USCIS petition approval and still need instructions for a later consular stage. Record which agency must act next, which reference it uses and what the approval actually covers. Do not send every immigration question to the same checker.
How to prepare a USCIS application or petition
- Identify the benefit and who files. Separate the applicant, beneficiary, petitioner and any representative. They are not interchangeable roles.
- Open the current official form details. Check the edition USCIS accepts, instructions, evidence requirements and relevant alerts.
- Confirm the filing method. Use the form’s current online or mail instructions. An account being available does not establish that every form or category can be filed through it.
- Verify the address if mailing. A filing address can depend on the form, category and delivery method. An agency headquarters address or nearby field office is not a substitute.
- Check fees and payment. Confirm the applicable amount, additional charges, permitted method and any exemption or waiver requirements.
- Review and preserve the record. Check signatures, names, dates and supporting documents. Save the submitted version, confirmation, payment record and subsequent notices.
Electronic-filing update: USCIS’s August 10, 2026 bulletin describes a rule allowing it to require e-filing for qualifying forms, with advance public notice. The rule’s existence does not mean all forms immediately became online-only. Check the current instructions for the particular filing.
USCIS fees: free forms do not mean a free application
USCIS states in its forms directory that official forms and online accounts are free. Many benefit requests still require a government filing fee. Optional preparation or legal-service charges are a third, separate cost.
Use the official filing-fees page and its linked fee schedule or calculator for your form and category. Record the filing method, applicable fee, any additional charge and the date checked. A single fee copied from a general comparison table may not describe your circumstances.
Payment matters: the current USCIS fee notice says paper-filed forms generally cannot be paid by personal or business check, money order or cashier’s check unless an exemption applies. It identifies card authorization using Form G-1450 or a U.S. bank-account ACH authorization using Form G-1650 for mail filings. Follow the current instructions; paying a correct amount through an unaccepted method can still cause a problem.
USCIS also announced inflation adjustments to certain immigration-related fees effective October 16, 2026. That announcement covers specified fees, rather than every USCIS form. Check current alerts and category-specific conditions instead of applying one announced increase to all applications.
Using a USCIS online account
Follow the official account-creation instructions linked above. Use an individual account, retain your recovery information and keep verification codes private. Creating an account or saving a draft does not submit an application.
USCIS explains how eligible paper-filed cases can be added to an account. Available features depend on the case and account instructions; an Online Access Code may be needed for certain functions. Keep that code separate from the receipt number used to identify a filing.
Use the account’s supported filing or response function for the actual task. Do not assume that uploading a document through any available screen satisfies a notice with a specified response method and deadline.
How to contact USCIS and find an appointment
The USAGov USCIS directory lists 1-800-375-5283 and TTY 1-800-767-1833. For calls from outside the United States, USAGov’s case-status guidance lists +1-212-620-3418. Use the USCIS Contact Center page for current service options and instructions.
Prepare your form, reference number, latest notice, exact issue and any deadline. For example: “My evidence-request notice has not arrived” describes a different problem from “I want to ask whether my case is outside normal processing.” Keep the support confirmation with the correct filing.
The official office directory says an appointment is required before visiting and instructs visitors to bring the printed appointment notice. Field offices, asylum offices and Application Support Centers perform different services. Use the location and instructions on your notice, check closures and follow the applicable rescheduling procedure if needed.
Our immigration office guide helps distinguish an office visit from a filing address or remote support request.
Common USCIS problems and the next useful action
| Problem | Check first | Next action |
|---|---|---|
| You cannot access the account | Account recovery and verification options | Use official account help; preserve notice deadlines separately |
| A receipt cannot be found online | Correct filing and reference from the receipt notice | Follow case-status help; a lookup error alone is not a decision |
| A notice asks for evidence | Complete notice, required evidence, delivery method and deadline | Respond through the specified route; seek qualified advice when necessary |
| You moved while a case is pending | USCIS address record and each pending receipt | Follow the address-change procedure, including any special population instructions |
| The case appears delayed | Any outstanding action and the correct processing-time selection | Use the applicable inquiry instructions when eligible |
Address changes need particular care. USCIS’s address-change page says most noncitizens subject to the reporting requirement must report a move within 10 days; it lists exceptions for A and G visa holders and visa-waiver visitors. Certain populations have specific procedures. Updating USPS does not update USCIS, and USCIS says USPS will not forward its mail. When using the online change tool, include the receipt numbers for each pending benefit request.
Avoid scams and obtain qualified help
The FTC advises against signing blank or false forms and against letting an adviser retain your original documents. Verify an attorney’s standing or an accredited representative’s authorization before paying for legal advice. A “notario” or consultant title does not establish authorization to practice immigration law in the United States.
Keep a private case worksheet: agency, form/category, reference, last notice, deadline, action, submission proof and next check date. For multiple filings, use a separate row for each. This practical record helps you ask a focused question without posting personal documents publicly.
Save a filing snapshot before submitting to USCIS
Because the United States Citizenship and Immigration Services handles different benefits and filing channels, keep a dated snapshot for the exact request you are submitting. A generic list of USCIS fees or a saved online draft is not enough to demonstrate that a filing is ready.
- Record the form number, current edition and eligibility category from the official form instructions.
- Check whether that category permits online filing, requires paper filing or has another specified channel. Keep the actual submission confirmation separately from account-registration emails.
- Check the fee for your category, any separately required charge, applicable exemption or waiver, and the accepted payment method. A waived base fee does not establish that every other charge is waived.
- For paper filings, copy the current mailing instructions for your request and delivery method. Do not use the nearest office’s street address just because it appears in a search result.
- Keep the completed packet and payment/submission evidence privately. Compare the later receipt with the request you actually sent.
The USCIS FY 2027 fee notice confirms that specified inflation-adjusted fees took effect October 16, 2026; it does not mean every form’s fee changed. If the problem is choosing a location rather than paying a fee, see the immigration office and appointment guide.
