You’ve seen the address. Maybe it’s on a piece of mail that’s making your palms sweat, or maybe you’re frantically typing it into your GPS while sitting in heavy traffic on the 101. 300 N Los Angeles Street. It’s not just a random building in the heart of Downtown LA. For thousands of people every single year, this specific spot represents the finish line—or sometimes a very stressful hurdle—in their quest for American citizenship or legal residency.
Most locals just drive past it without a second thought. It sits there, a massive, somewhat imposing federal structure known as the Edward R. Roybal Federal Building and United States Courthouse. But if you have business with the U.S. Citizenship and Immigration Services (USCIS), this location is basically the center of your universe.
What’s Actually Inside 300 N Los Angeles Street?
Honestly, the building is a bit of a labyrinth. It’s a multi-use federal facility, so you’ve got more than just one agency tucked away in there. While the USCIS Los Angeles Field Office is the primary reason people visit, the building also houses various federal courts and government offices. It’s named after Edward R. Roybal, a pioneer in LA politics who was the first Mexican-American elected to the LA City Council in the 20th century. Fitting, right?
When you walk in, you aren't just entering a post office or a DMV. This is a high-security federal environment. You’ll deal with TSA-style screenings—belts off, bags through the X-ray, the whole deal. If you’re coming here for a naturalization interview or an adjustment of status, your nerves are already shot. The sterile, quiet atmosphere of the lobby doesn't exactly help, but knowing where you're going once you clear security is half the battle.
The USCIS Connection
The Los Angeles Field Office located here handles a massive volume of cases. We are talking about one of the busiest districts in the entire country. This is where the magic happens—or where you’re asked to provide "one more document" that you swear you already sent twice. Specifically, this office deals with:

- Naturalization (Form N-400) interviews.
- Permanent Residency (Green Card) interviews.
- Civic testing for citizenship.
- Oath ceremonies (though the really big ones often move to larger venues like the LA Convention Center).
The Logistics of Visiting 300 N Los Angeles Street
Let’s be real: Downtown Los Angeles is a nightmare for parking. If your appointment is at 8:00 AM, you should probably be in the area by 7:15 AM. Why? Because the line to get into the building can sometimes wrap around the block, and finding a parking spot that doesn't cost $40 is like finding a needle in a haystack.
Most people try to find street parking, but that’s a gamble. You’re better off looking at the public lots on Main Street or Los Angeles Street. There are several "pay-by-day" lots nearby. They aren't cheap. Budget at least $15 to $25 for the day, because you never know if your 10:00 AM appointment will actually start at 10:00 AM or 1:00 PM. Federal time moves differently.
If you’re taking public transit, you’re in luck. The building is a relatively short walk from Union Station. You can hop on the Metro, walk a few blocks, and save yourself the headache of the 110 freeway.
What Most People Get Wrong About Their Appointment
I’ve talked to people who showed up at 300 N Los Angeles Street with their entire extended family. Don’t do that.

Security is tight, and space in the waiting rooms is limited. Generally, only the applicants, their attorneys, and necessary interpreters are encouraged to enter. If you’re there for a marriage-based green card interview, obviously both spouses go in. But leave the cousins at home. It just adds to the stress.
Another huge misconception? That you can just "walk in" to ask a question. Those days are mostly gone. USCIS moved to an appointment-only system (InfoPass) years ago. If you show up without an appointment letter or a very specific, pre-scheduled reason to be there, the guards will likely turn you away at the door. Use the USCIS online tools first. Save yourself the trip.
Surviving the Interview Day
The vibe inside the waiting room is... unique. It’s a mix of extreme boredom and high-stakes anxiety. You’ll see people in full suits and others in jeans.
Pro tip: Dress like you’re going to a job interview. It’s not a legal requirement, but first impressions with an immigration officer don't hurt.

The officers at 300 N Los Angeles Street are people too. They see hundreds of faces. They’ve heard every story. Being organized is your best defense against a long, grueling day. Bring a folder. Use tabs. If they ask for your birth certificate, you should be able to whip it out in three seconds, not dig through a grocery bag of loose papers.
The "Stuck in Limbo" Scenario
Sometimes, you go to 300 N Los Angeles Street, do your interview, and... nothing. The officer says your case is "under review." This is the part that drives people crazy. It doesn't mean you’re rejected. It often just means the officer needs to double-check a file or wait for a background check to clear. The Los Angeles office is notoriously backlogged because of the sheer volume of applicants in Southern California.
Essential Nearby Amenities

Actionable Steps for Your Visit
If you have a notice sending you to 300 N Los Angeles Street, do these things right now:
- Map it out today. Don't wait until the morning of your appointment to figure out which freeway exit to take.
- Check your documents twice. Ensure you have originals and photocopies of everything listed on your appointment notice. The office usually wants to keep the copies and see the originals.
- Bring a book. You cannot use your phone in certain sensitive areas of the building, and the wait times can be astronomical. A physical book or magazine is a lifesaver.
- Confirm the building entrance. Sometimes certain doors are exit-only. Look for the main entrance on Los Angeles Street where the security line forms.
- Double-check the date. It sounds silly, but people show up a day early or a day late all the time due to nerves.
The building at 300 N Los Angeles Street is more than just concrete and glass. It’s a gateway. Whether you’re there to become a citizen or to help a loved one stay in the country, respect the process, show up early, and stay organized. It’s a long day, but it’s often the start of a whole new chapter.
