A videotape of an immigration attorney, which provides advice on the right of U.S. citizens and visa holders to stop at the airport, aired on Tiktok, gaining more than 8 million views.

Posts by New York-based immigration attorney Brad Bernstein followed closely behind Tiktok users’ accounts, saying they were U.S. citizens but were detained for hours and were searched for phone or luggage when entering the country. These videos along with details Twitch streaming Hasan Piker shared videos about stopping and interrogating at the Chicago O'Hare International Airport - many wonder what rights were detained if U.S. customs officials were detained and what rights they had.

One of the biggest questions he heard was whether all constitutional rights are protected during the CBP screening.

"The Supreme Court ruled that the Constitution would not apply until you enter the United States of America," Bernstein said. "Although you are in the United States, you don't think you have entered the United States under immigration laws until you pass immigration and customs."

NBC News legal analyst Danny Cevallos explained that the Supreme Court ruled that “the routine searches at the border do not require an arrest warrant, and the possible causes are even reasonable suspicion, due to the government’s inherent sovereign interest in protecting its territorial integrity.”

Bernstein said personal protection depends largely on the traveler’s citizenship, while visa or green card holders have less protection.

"U.S. citizens must be allowed to return to the United States. The government cannot take your U.S. passport away, they cannot take your citizenship away," Bernstein said. But he advises being cautious.

"The airport has much lower constitutional authority standards and just walking around the local area on our streets, and this is the fourth amendment to illegal searches and seizures," he said.

Statistically speaking, advanced searches are rare, but it is important to plan ahead, Bernstein said.

He advises travelers who want to protect privacy through CBP can only use electronic devices that are absolutely necessary when traveling, log in to cloud-based services, and consider using auxiliary telephones when traveling abroad.

Most importantly, even if these searches can be daunting, it’s best to stay calm and tell the truth. "The more you say no, the more questions you will have. The longer you stay at the airport," Bernstein said.

According to the American Civil Liberties Union, U.S. citizens do not need to travel with them in the country to be citizenship.

"If you have valid immigration documents and are over 18 years of age, then the law does require you to carry these documents with you. If an immigration agent asks you to produce them, it is recommended to show them to the agent or you may be arrested."

Tiktok creator Savanna said she was a U.S.-born U.S. citizen, who said she was intercepted and interrogated by the CBP at an airport in Miami and asked the CBP for more than two hours. Her video about the encounter has received over 2 million views on Tiktok. In it, she describes the customs officials scrolling through social events and repeatedly asks her how much money she makes on Tiktok every day.

"I've been traveling abroad and have never had this problem," she told NBC News. "But one thing that happened between February and February was that I created Trump for the dump."

Savannah said the line was a satirical clothing brand she created with the goal of donating profits to humanitarian causes.

The Department of Homeland Security reposted Savanna's video on X and said she was not stopped due to political reasons.

"Legal travelers need not worry about these measures, and are designed to protect the security of our country," the Department of Homeland Security said in a statement. He added: "Accusing political beliefs of triggering inspections or evacuation is unfounded and irresponsible."

DHS said its data suggest that overall border search has increased since last year, but advanced screening has declined slightly.

Cevallos pointed to a recent federal case that determined that the search for “basic” electronic devices at the border was constitutional. "This has been criticized as an explanation for the Fourth Amendment threatening the privacy interests of the border," Cevallos said.

Piker, a streamer and American political expert, called Hasanabi on Twitch, said he believes he was stopped by the CBP during his return trip from France on May 11, a reason that DHS also questioned.

"I was invited to the back room to be questioned in many different things from Donald Trump to Donald Trump," he told NBC News.

Pique said he was not surprised when he was asked to resign by agents.

"I know it's likely to happen because I've heard a lot of reports about negative comments from immigration lawyers, even the Tiktoks and Donald Trump," he said.

Homeland Security spokesman Tricia McLaughlin said in an article on X that Piker "lied on 'like'.

“I think it’s really interesting because they admit it happened,” Pique said in response to McLaughlin’s post. “I think the part that I think is very evil is that it is an acknowledgement asking people about their loyalty to the current government or their perception of Israel-Palestine is part of a routine investigation?
