Send your I-130 to the USCIS service center that covers your state, not to a local office

The I-130 (Petition for Alien Relative) goes to one of four USCIS service centers based on where you live, not where your relative lives. You cannot walk it into a field office or mail it to the address on your green card. The service center you use depends entirely on your state of residence.

USCIS processes all family-based petitions at these four locations: Nebraska Service Center, Texas Service Center, Vermont Service Center, and California Service Center. Your state is assigned to one of them. Sending your petition to the wrong center will delay processing by weeks or months, as it will be forwarded to the correct location.

Key Takeaways

  • Your I-130 mailing address is determined by your state of residence, and USCIS publishes the complete list on its website under "Where to File".
  • Each of the four service centers has a different mailing address for I-130 petitions, and using the wrong one causes delays.
  • You must include the correct filing fee or a fee waiver request with your petition, or USCIS will return it without processing.
  • The I-130 is the first step in family-based immigration; your relative does not file anything until USCIS approves this petition.

How to find your service center by state

USCIS maintains a "Where to File" tool on its website that lists every state and its assigned service center. Go to uscis.gov, search for "Where to File I-130", and you will see a table showing your state and the corresponding service center name and mailing address.

The four service centers and their general coverage areas are: Nebraska Service Center (covers most Midwest and Mountain states), Texas Service Center (covers Texas, Oklahoma, Kansas, and some neighboring states), Vermont Service Center (covers Northeast and Mid-Atlantic states), and California Service Center (covers California, Hawaii, Guam, and some other Western states). However, do not guess based on geography—use the official tool, because some states are assigned to unexpected centers.

The correct mailing address for each service center

Each service center has a specific mailing address for family-based petitions. The addresses change occasionally, and using an outdated address will cause delays. Before you mail your petition, confirm the current address on the USCIS website under "Where to File" or on the I-130 form instructions (Form I-130, Instructions).

Do not mail to a USCIS field office in your city, even if you have visited it before. Field offices do not accept I-130 petitions by mail. If you attempt to hand-deliver your petition to a field office, they will tell you it must be mailed to the service center.

What to include with your I-130 petition

Your I-130 packet must include the completed form, supporting documents (birth certificate, marriage certificate, divorce decrees if applicable, proof of your immigration status), and the filing fee. The current filing fee for I-130 is $435, though this amount can change. If you cannot afford the fee, you may include a Form I-912 (Request for Fee Waiver or Reduction) instead of the fee.

USCIS will return your entire petition if the fee is missing and you have not submitted a fee waiver request. Include a check or money order made payable to "U.S. Department of Homeland Security"—do not send cash. Write your name and the form number (I-130) on the back of the check.

How long processing takes after you mail it

After USCIS receives your I-130 at the service center, you should receive a receipt notice (Form I-797) within two to three weeks. This receipt shows your case number and confirms USCIS has your petition. Processing time for the I-130 itself varies by service center and current workload, typically ranging from several months to over a year.

You can track your case using the case number from your receipt notice on the USCIS website under "Check Your Case Status". Do not contact the service center by phone before receiving your receipt notice; they cannot look up cases that have not yet been logged into the system.

What happens after USCIS approves your I-130

Once USCIS approves your I-130, your relative becomes may be able to access to move forward with their visa process. If your relative is outside the United States, they will file consular processing forms with the National Visa Center (NVC). If your relative is already in the United States, they may be able to adjust status through USCIS.

The I-130 approval does not mean your relative has a visa yet—it means the family relationship has been verified and they can proceed to the next step. Your relative will receive separate instructions about what to do next based on their location and immigration status.

Common mistakes that delay your petition

The most frequent errors are mailing to the wrong address, omitting the filing fee or fee waiver, and not signing the form. USCIS will reject unsigned petitions. Also, do not include original documents if you can avoid it—send copies instead, because USCIS does not return originals. If you must send an original (such as a birth certificate from another country), include a photocopy as well.

Another common mistake is submitting an I-130 before you have confirmed your own immigration status is current. If you are the petitioner, USCIS will verify that you are a U.S. citizen or lawful permanent resident. If your status has lapsed or is in question, resolve that before filing the I-130.

Frequently Asked Questions

Can I email or fax my I-130 instead of mailing it?

No. USCIS only accepts I-130 petitions by mail to the service center address. Email and fax submissions are not processed. Use certified mail or a tracked delivery service so you have proof of mailing.

What if I move to a different state after I mail my I-130?

You do not need to resubmit your petition. Once USCIS receives it at the correct service center, your case stays there even if you move. Notify USCIS of your address change using Form AR-11 (Change of Address) so they can mail you updates at your new address.

Do I need to include a cover letter with my I-130?

A cover letter is not required, but many people include one listing what documents are enclosed. This is optional and does not speed up processing, but it can help you stay organized and gives you a record of what you sent.

Can my relative file their own I-130, or does the petitioner have to file it?

The petitioner (the U.S. citizen or lawful permanent resident) must file the I-130. Your relative cannot file it on their own. The petitioner is the one who proves the family relationship to USCIS.

What if the service center loses my petition?

If you do not receive a receipt notice within three weeks of mailing, contact USCIS using the online case status tool or call their customer service line. Have your name, date of birth, and mailing date ready. If your petition was lost, USCIS will advise you to resubmit it.
