Family members and his friend say there has been no phone activity or updates since the initial message from the airport detention area. In CBP custody cases, phone access is often extremely limited or completely restricted after initial processing, especially once formal detention begins. Valid Visa Rejected on Arrival at LAX byu/purealgo inimmigration"Shortly after arriving, he briefly got access to his phone for about 5 minutes and messaged me that his visa had been denied and that they were holding him. Since then, his phone has been completely inactive, and we haven’t heard anything further. His family is understandably very worried," the post stated.Why Entry May Have Been DeniedWhile officials have not publicly confirmed the reason, the case has sparked discussion around possible immigration violations linked to previous travel history. Even suspected violations from past visits can trigger stricter scrutiny during re-entry.Reports suggest the traveller had earlier stayed in the US for around 4–5 months during a prior visit. Although he did not overstay, it is alleged that he may have done short-term informal work during that period—something strictly prohibited under a tourist visa."He visited the U.S. about 7-8 months ago and stayed for roughly 4-5 months. He did not overstay his authorized period of admission. However, while he was here, he ran low on money and did some under the table food delivery work for a short time.My guess is that CBP may have discovered this and concluded that he violated his visa. Does that seem like a likely reason for being denied entry?," the post explained.What CBP Custody Actually MeansWhen a traveller is denied entry at a US port of entry, they are placed under CBP supervision until removal arrangements are completed.This usually involves:Secondary processing at the airportTemporary holding in restricted facilitiesLimited or no communication accessCoordination for return travelIn most cases, the individual is eventually placed on a return flight to their home country.How Long Can Someone Be Held?There is no fixed timeline for CBP detention after entry denial. The duration depends on several factors, including:Availability of return flightsCompletion of immigration paperworkSecurity and background checksAirline coordination for deportationWhile some cases are resolved within 24–72 hours, others may take longer depending on logistical delays.What Happens After Entry Is RefusedOnce US authorities deny entry, the traveller is typically:Issued expedited removal or withdrawal of admissionHeld until deportation is arrangedSent back on the next available flightThe incident is also recorded in immigration databases, which can impact future visa applications and travel eligibility.Why US Immigration Rules Are Strict at AirportsEven with a valid visa, entry into the United States is not guaranteed. CBP officers have the final authority to decide whether a traveller can enter the country. They may deny entry if they suspect:Previous visa misuseUnauthorised workInconsistent travel historyMisrepresentation of purpose of visitRising Concerns Among Frequent TravellersCases like this have triggered discussion among international travellers about stricter border enforcement in the US.While most visa holders enter without issues, secondary inspection and denial at the port of entry remain a legal possibility based on officer discretion and travel history review.Disclaimer: This article is based on a user-generated post on Reddit.
