About this crossing
Marcelino Serna, TX (Tornillo) is a US Customs and Border Protection port of entry on the Mexican border. Wait times shown are for travelers entering the United States. Numbers come directly from CBP and update roughly every hour while the port is staffed.
Frequently asked
Do I need a passport to cross at Marcelino Serna, TX?
Yes. US citizens need a passport, passport card, enhanced driver's license, or SENTRI card. Non-US citizens need a valid passport plus any required visa.
Are SENTRI lanes always faster?
SENTRI lanes are typically much faster than standard lanes, especially at peak times, but they can still see delays when traffic is heavy or when a few lanes are open. SENTRI provides expedited US entry for pre-approved low-risk travelers from Mexico. Apply at ttp.cbp.dhs.gov.
What hours is the Marcelino Serna crossing open?
6 am-10 pm. Hours are set by CBP and may change for holidays or staffing.
How often is this wait time updated?
CBP officers at each port update their reported wait time roughly every hour while the port is staffed. We re-poll the CBP feed every five minutes and cache the result for both speed and to be kind to the upstream feed.
Why is the wait time blank or "no data"?
CBP doesn't publish a number for that lane right now — usually because the port hasn't reported in over an hour, the lane is closed, or the port is idle. We show whatever CBP publishes without modification.
