Electronic device searches by U.S. Customs and Border Protection (CBP) have significantly increased at international airports, ports, and border crossings, according to a new report. The number of searches on mobile phones, laptops, tablets, and other electronic devices is expected to rise by 42.3%, from 33,062 in 2018 to 47,047 in 2024. These searches are part of CBP’s efforts to identify potential threats and protect U.S. borders from various illegal activities.
CBP officials explain that the ability to inspect electronic devices crossing U.S. borders is crucial to ensuring national security in today’s increasingly digital world. “As responsible for protecting our borders and enforcing numerous laws at ports of entry, the ability of CBP to lawfully inspect electronic devices is essential to keeping our nation safe,” a CBP notice stated earlier this year. All travellers crossing the U.S. border, regardless of citizenship, are subject to customs inspections, including searches of their electronic devices such as cell phones, computers, and cameras.
These device searches are primarily used to combat terrorism, child pornography, drug smuggling, human trafficking, export control violations, intellectual property theft, visa fraud, and other criminal activities. Additionally, they help determine an individual’s intent to enter the U.S. Although only 0.01% of travellers have been subject to electronic device searches in fiscal year 2024, there have been instances where individuals have faced arrest or denial of entry after seemingly unrelated files, such as text messages or computer data, were found during a search.
In one notable case from 2017, a man traveling from Korea was arrested for possessing child pornography on an external hard drive, leading to a prison sentence. In another case, a foreign student was deported after CBP used a Korean interpreter to review messages on the messaging app KakaoTalk, which revealed the student had been working illegally at a restaurant.
CBP conducts two types of searches: basic and detailed. Basic searches involve manually reviewing the contents of a device without any additional tools, while detailed searches use external equipment to access stored data. In 2024, out of 420,521,616 travellers entering the U.S., 12,667,84 people underwent secondary searches, and 42,725 basic searches and 4,322 detailed searches of electronic devices were performed. Of these searches, 36,506 were on non-citizens, while 10,541 were on U.S. citizens.
Current entry guidelines state that travellers whose electronic devices are selected for investigation may be required to decrypt their devices to provide information. While citizens can refuse to answer questions beyond identity and travel details, this can result in delays. However, visa holders who refuse to answer such questions risk being denied entry. A significant concern remains the potential leakage of sensitive personal information during the process of sharing passwords to access devices, raising privacy risks for travellers.
