Send your green card process to USCIS, but the exact address depends on your category and where you live

You do not send a green card process to one central office. Instead, you mail it to a USCIS Service Center that handles applications from your region. The address changes based on whether you are explore through family sponsorship, employment, diversity visa, or another category. The form itself — usually Form I-485 (process to Register Permanent Residence or Adjust Status) — tells you which Service Center to use, and USCIS also publishes a complete list on its website organized by state.

If you are adjusting status inside the United States, you mail the process to the Service Center that covers your state. If you are explore from outside the US through consular processing, your process goes to the National Visa Center (NVC) first, not directly to a Service Center. The NVC then forwards your case to the appropriate US embassy or consulate abroad. Getting the address wrong delays your case, so checking the current instructions before you mail is essential.

Key Takeaways

  • USCIS Service Centers are organized by region, and the correct address depends on your state and process type, which is listed in the form instructions.
  • If you are adjusting status in the US, you mail Form I-485 to the Service Center covering your state; if you are explore from abroad, your case goes to the National Visa Center first.
  • USCIS publishes the current mailing addresses on its website because addresses and procedures change, so always check the official form instructions before mailing.
  • Mailing your process to the wrong address will delay processing, so confirm the address matches your specific situation and state.

The four USCIS Service Centers and which states they cover

USCIS operates four regional Service Centers, each handling applications from specific states. The Nebraska Service Center covers Alaska, Colorado, Hawaii, Idaho, Illinois, Indiana, Iowa, Kansas, Michigan, Minnesota, Missouri, Montana, Nebraska, North Dakota, Ohio, South Dakota, Utah, Wisconsin, and Wyoming. The Texas Service Center covers Arkansas, Louisiana, Oklahoma, Texas, and Mississippi.

The Vermont Service Center covers Connecticut, Delaware, Maine, Massachusetts, Michigan, New Hampshire, New Jersey, New York, Pennsylvania, Rhode Island, Vermont, and West Virginia. The California Service Center covers Arizona, California, Guam, Hawaii, Nevada, and Northern Mariana Islands. Some states appear in multiple regions because USCIS has adjusted boundaries over time. Always check the form instructions or the USCIS website to confirm which Service Center handles your state, because mailing to the wrong one adds weeks to processing.

How to find the exact mailing address for your process

The safest way to find your correct mailing address is to read the instructions that come with the form you are filing. Form I-485 (Adjustment of Status), Form I-140 (Immigrant Petition for Alien Worker), and other green card forms all include a section titled "Where to File" that lists the Service Center address for each state. The instructions are updated regularly, so an address you used two years ago may have changed.

You can also visit the USCIS website and search for "Service Center addresses" or the specific form number. The website displays addresses by state and form type. Write down the complete address, including the ZIP code, before you prepare your process. Some Service Centers have separate addresses for regular mail and overnight courier services, so check whether you are mailing or using FedEx or UPS.

Adjustment of status versus consular processing: where each goes

Adjustment of status means you are already in the United States and filing your green card process here. You mail Form I-485 directly to the USCIS Service Center that covers your state. You do this after your immigrant petition (Form I-140 or I-130) has been approved and a visa number is available to you. Processing typically takes several months, and you can work and travel while your case is pending if you file the right forms at the same time.

Consular processing means you are living outside the United States and will complete your green card process at a US embassy or consulate in your home country. You do not mail Form I-485 to a Service Center. Instead, after your immigrant petition is approved, your case goes to the National Visa Center (NVC) in Portsmouth, New Hampshire. The NVC collects documents from you, and then your case moves to the embassy or consulate where you will have your final interview. The NVC will send you instructions on where and how to submit documents — usually online through their portal.

What happens after you mail your process

Once the Service Center receives your process, you should receive a receipt notice (Form I-797) within two to three weeks. This receipt shows your case number and tells you whether USCIS accepted your process or needs more information. Keep this receipt because you will need the case number to check your case status online or contact USCIS about delays.

Processing time varies widely depending on the Service Center, your category, and current workload. Some cases are approved within four to six months; others take a year or longer. You can check your case status on the USCIS website using your case number and receipt date. If you do not receive a receipt notice within three weeks, contact the Service Center to confirm they received your process.

Common mistakes when mailing your green card process

The most common error is mailing to the wrong Service Center. This happens when applicants use an old address, mail to the main USCIS office in Washington DC, or guess based on where they think the office is located. Always use the address in the current form instructions, not an address you remember from before.

Another mistake is not including all required documents. USCIS will return incomplete applications, which delays everything. Make a checklist from the form instructions, gather every document, and make copies for your records before mailing. Do not mail original documents unless the instructions specifically require it — send certified copies instead.

A third mistake is not keeping a copy of what you mailed. Before you send your process, photocopy every page and every document. Store these copies safely. If USCIS says they never received something, you have proof of what you sent. Also, do not mail cash or checks unless the instructions say to do so — most applications are filed without payment at this stage.

Tracking your process after you mail it

Use a mailing method that provides tracking, such as certified mail with return receipt or an overnight courier service. This way you have proof the Service Center received your process. Write down the tracking number and keep it with your receipt notice.

After you receive your receipt notice, check your case status regularly on the USCIS website. Go to uscis.gov, click "Check Your Case Status," and enter your case number and date of birth. The website will tell you whether your case is pending, approved, or if more information is needed. If your case status does not change for several months beyond the normal processing time, contact the Service Center by phone or through the USCIS online inquiry system.

Frequently Asked Questions

What if I mail my process to the wrong Service Center?

USCIS will likely return it to you or forward it to the correct Service Center, which delays processing by several weeks. To avoid this, always check the current form instructions before mailing. If you realize you mailed to the wrong address, contact the Service Center you mailed to and ask them to forward your case, then follow up with the correct Service Center to confirm they received it.

Can I hand-deliver my process instead of mailing it?

Most USCIS Service Centers do not accept hand-delivered applications. You must mail your process or use an authorized courier service. Some local USCIS offices accept in-person filings for specific forms, but green card applications are not typically among them. Check the form instructions to see if your Service Center accepts courier delivery.

Do I mail my process before or after my immigrant petition is approved?

You mail your green card process (Form I-485) after your immigrant petition (Form I-140 or I-130) has been approved and a visa number is available to you. If you mail before approval, USCIS will reject it. Your petition approval notice will tell you when you can file your adjustment process.

What if I am filing from outside the US — do I still mail to a Service Center?

No. If you are explore through consular processing, your case goes to the National Visa Center in Portsmouth, New Hampshire first, not to a Service Center. The NVC will contact you with instructions on how to submit your documents, usually through their online portal. You will not mail anything to a Service Center in this situation.

How do I know if my process was actually received?

Send your process using certified mail with return receipt or an overnight courier service so you have proof of delivery. USCIS will send you a receipt notice (Form I-797) within two to three weeks if they accepted your process. If you do not receive a receipt notice after four weeks, contact the Service Center using the phone number on the form instructions.
