How to Change the Address on a US Green Card

If you are an Australian citizen or permanent resident who holds a U.S. green card, moving does not automatically update your U.S. immigration record. USCIS generally requires you to report a new address within 30 days of the change. This applies to a new house or apartment in Sydney, a move to Melbourne, and a relocation to another country. Your green card remains your proof of permanent residence; the filing changes the address in government records rather than replacing the card.

There are two separate administrative trails to keep in mind: the U.S. address registered with USCIS and, if relevant, your Australian visa or personal details. They are not linked automatically. The U.S. process involves a particular immigration form, whereas Australian residents usually manage their own records through ImmiAccount and service providers such as banks, landlords and electricity companies.

When USCIS Needs to Be Told

A change of address must generally be filed within 30 days of moving. This includes moving to a different street, unit, building, rural route or town, as well as moving between U.S. states. If you are leaving the United States for good, file before your departure and give your new overseas mailing address. A temporary visit does not necessarily constitute a change if you continue to live at the same home and do not establish a separate mailing address.

The form normally asks for both your mailing and physical address. These can be the same, but an Australian mailing address is acceptable even while you still live in the United States. If you have already moved to Brisbane, for example, your Australian home can be the mailing address and the place you physically live. If you are temporarily abroad but intend to return to your American home, explain that arrangement rather than inventing a U.S. address.

Do not wait for the new address to appear on a bank statement, lease or utility bill. File using the address where you will receive U.S. correspondence, and make sure someone can receive it there. The physical card is not amended, punched or replaced for an address change, so do not surrender it or mark it yourself.

The Correct Form and Filing Route

The standard route is Form I-485, Application to Register Permanent Residence or Adjust Status, with Form I-485 Supplement C, Part 11, Change of Address. Supplement C by itself is not a complete address-change application. If you are already filing Form I-485 to adjust status, include the relevant supplement with that application instead of filing a separate case.

You can submit the paperwork by mail or, if your situation is eligible, through a USCIS online account. For a paper filing, use the USCIS service centre or lockbox address specified in the current Form I-485 instructions; the correct destination depends on the filing circumstances. If an immigration lawyer or authorised representative handles your case, follow their instructions about filing and correspondence.

USCIS currently lists an $85 filing fee for Form I-485 and may add an $85 biometrics fee when biometric services are required. Confirm the amounts and payment method on USCIS’s official fee pages before sending anything. Make the payment payable to U.S. Citizenship and Immigration Services, use the correct form edition, and sign where the form requires a signature.

Information and Evidence to Gather

Before completing the form, collect the following details. Having them in one place reduces the chance of a rejected filing.

• Your full legal name as shown on the green card, date of birth and U.S. alien registration number, commonly called an A-number, if known.
• Your complete new address, including unit or apartment, street, suburb or city, state or territory, four-digit postcode and country.
• Your former address, the date you moved and the telephone number and email address USCIS should use.
• The receipt number from a recent I-485 filing or a previous address-change filing, if you have one.
• Details of any representative, including their full name, address, email address and agreement about who will receive USCIS notices.

Next, gather evidence that supports where you live. The following documents can be useful, depending on your circumstances.

• A bank statement showing your name and current residential address.
• A residential lease, tenancy agreement, property document or electricity, gas or internet bill.
• Correspondence showing that you receive mail at the new address, especially if it connects your name to the property.
• If you live outside the United States, evidence of your foreign address and, where relevant, your visa or entry record.

There is no single document that USCIS requires for every address change, and an unfamiliar document can lead to a request for more evidence. A recent statement from an Australian bank such as ANZ, Commonwealth or Westpac can help show your connection to an Australian residence; a landlord’s lease or an electricity bill may add useful support. If older records are all you have, include a short explanation of why more recent proof is unavailable.

Australian addresses need careful transcription on U.S. forms. Write the suburb and state, then the postcode, rather than using a U.S. “ZIP code” or “city” field in a way that confuses the two systems. For example, “Richmond VIC 3121, Australia” needs the street and unit details as well. If the address will not fit in the available space, add a continuation sheet with your name, A-number or receipt number and the complete address.

Submit the Change and Avoid Delays

For a paper application, check the destination against the instructions every time you file, because USCIS can change lockbox arrangements. Put the form, supplement, fee and requested evidence in one envelope addressed to the correct office. Keep a complete copy and dated proof of posting or courier delivery. For an online filing, save the confirmation, submitted documents and receipt number. Never send your original passport or green card unless the official instructions specifically require it.

The most frequent administrative problems are an incomplete supplement, an incorrect fee, a missing signature or mailing to the wrong office. Review every field, including the new address, date of change and contact details. USCIS may issue a request for evidence or a notice of action, so treat any response as time-sensitive rather than assuming that filing the first form finishes the matter.

Mail forwarding is not notification to USCIS. An Australia Post redirection service or a USPS forwarding request can keep your mail moving, but neither tells the immigration agency that you moved. Likewise, an Australian PO box is not automatically suitable for U.S. government correspondence. A secure street address where someone can sign for documents is usually more dependable for this filing.

What Happens After Filing

USCIS normally issues a receipt, often Form I-797C, with a receipt number you can use to check the case online. A routine address change does not usually require an interview and does not produce a replacement green card. The agency updates the address in its records once the filing is accepted. If the card itself has expired or been damaged, that is a separate issue requiring the appropriate application; an address change does not renew it.

Keep watching both your new and old email addresses for notices until the change is recorded. If you move again before USCIS processes the first request, submit another address-change request for the newer address. If family members living with you need their own immigration records updated, each person needs a separate request; one person’s filing does not update everybody’s record.

Other organisations do not receive automatic notice. Update your state motor vehicle licence with the relevant U.S. agency under its own deadline, and consider notifying the Social Security Administration if you are in the United States and eligible to do so. If you also hold an Australian permanent visa, check your address through ImmiAccount. A green card update has no effect on your Australian visa record or Australian banking details, so those systems need separate attention.

The practical action is straightforward: prepare Form I-485 with Supplement C, file it within 30 days of the change and retain proof of the filing. If the deadline has already passed, submit the request promptly rather than waiting for your next immigration application, and use the current USCIS instructions and fee schedule. If the situation is complicated or a government deadline is close, obtain advice from a lawyer qualified in U.S. immigration law.

Make the filing, keep the receipt and check your correspondence. That administrative step keeps your U.S. permanent residence record accurate and helps ensure future immigration mail can reach you.
