San Luis Rio Colorado Border Crossing Wait Time: Port of Entry 1-2

There are two ports of entry in San Luis Río Colorado, Sonora, connecting to San Luis, Arizona (AZ), on the U.S. side. They're a few minutes apart and serve different types of traffic:

San Luis Río Colorado I: Operating hours for this line are 24 hours, 7 days a week

This is the main line crossing and the one most people use. It handles both vehicle and pedestrian traffic, including tourist lanes, and never closes. If you're crossing at night or early in the morning or as a pedestrian, this is your only option.

San Luis Río Colorado II: Line open from 9:00 AM to 5:00 PM daily

Line II is a dedicated commercial crossing, primarily for freight and commercial vehicles. It keeps more limited hours, so if you're arriving after 5:00 PM, plan on Line I instead. Pedestrian crossing is not available for this line.

The waiting line for crossing into San Luis, Arizona, starts on the Mexican side of San Luis Río Colorado, Sonora. Line I: The 24-hour crossing handles pedestrian and vehicle traffic through its tourist lanes. The live report on Bordergarita shows you current wait times for each border crossing before your departure, so that you can plan your route to the port of entry/line accordingly.

We are also adding a new trend indicator in our report, which shows whether wait times are rising, holding steady, or falling. This is useful if you have a few minutes of flexibility in when you head out.

The requiered documentation needed depends on which side of the border you're from, and your nationaltionally or legal status:

U.S. Citizens and Lawful Permanent Residents

A valid U.S. passport, passport card, or Enhanced Driver's License (EDL) is accepted at each border crossing ( San Luis Río Colorado line I and line II). The passport card is a popular choice for frequent land crossers; it is a cheaper option than the full passport book and easy to carry, though it doesn't work for international air travel.

Mexican Citizens

A valid Border Crossing Card (BCC), the laser visa, is required at the San Luis Río Colorado port of entry. If you're planning to travel more than 25 miles (40 km) beyond San Luis, Arizona (AZ), you'll also need a Form I-94. You can apply for it ahead of time at i94.cbp.dhs.gov rather than dealing with it at the crossing itself.

Bordergarita.com has a live wait time report for each border crossing at San Luis Río Colorado, Line I and Line II, updated every five minutes with data from CBP's Border Wait Times system.

You can also check wait times for this border crossing and more from the same page: Mexicali, Nogales, Algodones, and the rest of Baja California and Sonora, which we all covered.

The most practical option for regular crossers is SENTRI, Secure Electronic Network for Travelers Rapid Inspection. SENTRI gives you access to dedicated, faster lanes and can cut your crossing time by up to 90% compared to standard lanes during peak hours.

The process requires a background check and an in-person interview at a CBP enrollment center. It's not instant, and approval isn't guaranteed, but for people who cross San Luis Río Colorado weekly, or more, the time savings add up fast.

Requirements and the full application are at the official CBP Trusted Traveler Programs website (http.cbp.dhs.gov). Fee structures and documentation requirements do change, so always check the official site directly rather than relying on third-party summaries.

Wait times here follow the same general patterns as most Southwest border crossings:

Weekday mornings before 8 AM tend to be the lightest, especially Monday through Thursday.

Friday afternoons are reliably busy as weekend travel picks up on both sides.

Sunday evenings see heavy return traffic into the U.S., one of the consistently worst windows of the week.

Holiday weekends, especially around Thanksgiving, Christmas, and Fourth of July, can add an hour or more to typical wait times.

That said, San Luis, Río Colorado has its own local patterns that don't always match broader trends. Check the live report on Bordergarita before you leave. Rather than going on general rules, the trend indicator will tell you if things are moving in the wrong direction.

CBP enforces the same federal list of prohibited and restricted items at every U.S. port of entry. The ones that come up most often at Southwest border crossings, like San Luis Río Colorado:

Fresh produce and foods with seeds, fruits, vegetables, and plants are generally not allowed to cross. Commercially packaged items are usually fine.

Exotic animals are prohibited without specific federal permits and health documentation.

Weapons and firearms; strict federal regulations apply. Crossing with an undeclared firearm is a federal crime.

Controlled medications; a valid prescription is required, and only quantities for personal use are allowed.

Live plants and cut flowers are subject to agricultural inspection and often restricted.

Cash or monetary instruments over $10,000 USD are legal to carry, but must be declared at the crossing. Failure to declare is the offense, not the amount.

The full list is at cbp.gov. If you're unsure about something specific, it's worth checking before you get in line rather than after.

Locals on the Mexican side most often call it simply "la fila", the line, or refer to crossing as going to "San Luis, Arizona" or "el otro lado" (the other side). You'll hear phrases like "¿cómo está la fila?" or "¿dónde va la fila?" among regular crossers in San Luis Río Colorado.

On the U.S. side, it's typically referred to as the "San Luis Port of Entry" or the "San Luis, Arizona border crossing." CBP officially lists each border crossing, as the San Luis Line I and San Luis Line II Port of Entry.

Yes. Our official Facebook group "¿Dónde va la fila San Luis Río Colorado?" shares official CBP wait time data and community reports from people actually at the crossing. Members post photos and real-time updates from the line, which is particularly useful when official data lags what's actually happening at the booths.

You're welcome to join, share updates while you wait, and follow the live report that way if it works better for you than the website.
