Digital Border

For many travelers, a personal phone is an inviolable space containing private conversations, photos, banking data, and work information. However, under the principle of international law, when you cross another country's border, your "expectation of privacy" diminishes. States have a sovereign right to inspect everything entering their territory, whether it's physical luggage or digital information.

In the US, a principle applies whereby Customs and Border Protection officers have the authority to conduct a search without a warrant.

• Basic inspection: an officer can ask you to unlock your phone and review the files on it.
• Extended inspection: if there is reasonable suspicion, they can send the device to a special lab for a full copy of the data.
• Refusal: if you are not a US citizen or permanent resident, refusing to unlock your phone may result in denial of entry and deportation.

Canada's border service also has the authority to search a traveler's mobile phone. However, based on recent court rulings, officers in Canada need "solid grounds" or "reasonable cause" to search a personal device. Under Canadian law, a phone is treated not as mere "luggage," but as a person's private space, which somewhat limits arbitrary searches.

There is a group of countries where digital searches are not the exception but often a routine procedure, especially for people of certain professions or nationalities.

At some Chinese border checkpoints (particularly in the Xinjiang region), there have been documented cases where border officers ask tourists to install special software that scans the phone to detect "extremist" or banned content.

Israeli border officers have the right to request access to your email and social media accounts (Facebook, Instagram) if they believe your visit could pose a threat to national security. Refusal usually results in a ban on entry.

In Russia, digital control is among the strictest. Since late 2024, Russia has begun an experiment involving biometric data collection and the creation of a "digital profile" for foreigners at Moscow's airports.

Officers of Russia's Federal Security Service often conduct so-called "secondary line" interrogations at the border. They primarily look for:

• Political stance: correspondence, photos, or symbols related to Ukraine.
• Banned content: connections to "undesirable organizations," encrypted messengers, and VPN applications, which become additional grounds for suspicion.
• Recovered information: software is often used at Russian border checkpoints that can recover even deleted messages.

Today, border officers pay attention not just to what you own, but also to what you write.

• Mismatch with the purpose of the visit: if you enter a country on a tourist visa, but a WhatsApp conversation about job searching is found, this is direct grounds for canceling the visit.
• Posts and "likes": in some countries, posts critical of the government can become grounds for detention or deportation.

If you're planning to travel to a country with strict border controls, experts offer the following recommendations:

Backup copies: make a full backup of your phone to a cloud server and delete sensitive information from the device.

Two-factor authorization: use security measures, but keep in mind that hiding a password at the border may be considered an offense.

Be polite: arguing with a border officer only increases suspicion. Refusal often means being denied entry into the country.
