Send your green card process to USCIS, but the exact address depends on whether you are adjusting status inside the United States or consular processing abroad

If you are already in the United States and adjusting status through USCIS, you send Form I-485 and supporting documents to a USCIS lockbox — a find mail facility that sorts incoming applications. The lockbox address depends on your state of residence. If you are processing through a U.S. embassy or consulate abroad, you send documents to that specific consulate, not to USCIS headquarters.

The distinction matters because the two paths use different forms, different addresses, and different processing timelines. Sending your process to the wrong address delays your case and may require you to resubmit. The USCIS website lists current lockbox addresses by state, and those addresses change occasionally, so checking the official site before you mail is essential.

Key Takeaways

  • Adjustment of status applications go to a USCIS lockbox in your state; the address is listed on the Form I-485 instructions page and varies by location.
  • Consular processing applications go directly to the U.S. embassy or consulate handling your case, not to USCIS.
  • USCIS lockbox addresses change periodically, so verify the current address on the official USCIS website before mailing.
  • Using the wrong address causes delays and may require you to resubmit your entire process package.
  • You can also file Form I-485 online through the USCIS online filing system if you are may be able to access, which eliminates the mailing address question.

Finding the correct lockbox address for adjustment of status

When you adjust status inside the United States, USCIS directs all Form I-485 applications to regional lockboxes. The address you need is printed on the Form I-485 instructions, which USCIS updates regularly. Do not rely on an old form or an address you find elsewhere — use the current instructions from USCIS.gov.

To find your lockbox address, go to USCIS.gov, search for "Form I-485 instructions," and read the PDF. The instructions list lockbox addresses by state. Your state of residence determines which lockbox receives your process. If you move before your case is decided, you do not change the lockbox address; you notify USCIS of your address change separately using Form AR-11 or through your online USCIS account.

The lockbox system exists to handle volume and prevent mail from being lost in a general office mailroom. Mail sent to USCIS field offices or headquarters is rejected and returned to you, which delays your case by weeks or months.

Consular processing: sending documents to your embassy or consulate

If you are processing your green card through consular processing — meaning you are abroad and will receive your visa at a U.S. embassy or consulate — you do not send documents to USCIS at all. Instead, you send them to the National Visa Center (NVC) first, and the NVC forwards your case to the consulate.

The NVC is a contractor that handles visa cases before they reach the consulate. You will receive instructions from NVC about where to send your documents and what forms to include. Once NVC processes your case, it sends everything to the specific consulate where you will have your interview. That consulate then contacts you directly with interview scheduling and any additional document requests.

The consulate address is not something you choose — it is determined by your country of residence and your visa category. NVC will tell you which consulate is handling your case.

Using USCIS online filing instead of mailing

USCIS now allows certain applicants to file Form I-485 online through the USCIS online filing system. If you are may be able to access, online filing eliminates the need to find a lockbox address and mail physical documents. You upload your forms and supporting documents directly to your USCIS account.

Not all cases are may be able to access for online filing yet. The system is expanding, but some visa categories and situations still require paper filing. Check the Form I-485 instructions or your USCIS account to see whether online filing is an option for you. If it is available, it is usually faster than mailing because USCIS receives your documents when ready and can begin processing without waiting for mail delivery.

What happens after you mail your process

Once the lockbox receives your process, USCIS scans it and creates a case file in their system. You will receive a receipt notice (Form I-797) by mail within two to three weeks, which includes your case number and a temporary receipt number. That receipt number is how you track your case online.

Do not assume your process was received if you do not get a receipt notice within three weeks. Contact USCIS using your receipt number or case number to confirm. If your process was lost in the mail, you will need to resubmit it, so keeping copies of everything you send is important.

Common mistakes that delay your case

Sending your process to a USCIS field office instead of the lockbox is the most common error. Field offices do not process I-485 applications and will return them to you, costing you four to eight weeks. Always use the lockbox address from the current Form I-485 instructions.

Using an outdated lockbox address is also common. USCIS changes lockbox addresses occasionally, and an address that was correct two years ago may no longer be active. Check the instructions every time you file, even if you have filed before.

For consular processing, sending documents to USCIS instead of NVC is a frequent mistake. Your case will be rejected and returned, and you will have to start the NVC process over. Make sure you understand whether you are adjusting status or doing consular processing before you mail anything.

Tracking your process after you send it

Once you have your receipt number, you can check your case status on USCIS.gov using the case tracker. Enter your receipt number or your online account login to see whether USCIS has received your process, whether it has been assigned to an officer, and whether any requests for additional documents have been issued.

If you filed online, you can also check your USCIS account directly for messages and document requests. Online filers often receive updates faster because USCIS does not have to wait for mail delivery to begin processing.

Frequently Asked Questions

Can I send my green card process to a USCIS office in person instead of mailing it?

No. USCIS does not accept I-485 applications at field offices. You must mail to the lockbox or file online. Bringing documents to a field office will not start your case and may result in them being lost.

What if I mail my process to the wrong address?

It will be returned to you, usually with a notice explaining why. You will then need to remail it to the correct lockbox address. This delay can add four to eight weeks to your processing time. Check the current Form I-485 instructions before mailing to avoid this.

Do I need to use certified mail or signature confirmation when sending my process?

It is not required, but many applicants use it for peace of mind. Regular mail works fine and is what most people use. If you do use certified mail, keep the receipt so you can prove delivery if there is a problem.

How do I know if I should adjust status or do consular processing?

Your visa category and immigration status determine which path you take. If you are already in the United States on a valid visa or status, you usually adjust. If you are abroad, you usually do consular processing. Your immigration attorney or the USCIS website for your visa category will confirm which applies to you.

Can I change my address after I mail my process?

Yes. Once you receive your receipt notice, you can update your address online through your USCIS account or by mailing Form AR-11. Do this as soon as you move so USCIS can reach you with updates or requests for documents.
