Question 1

Do noncitizens face a risk of being arrested by immigration enforcement authorities when taking US domestic flights?

Accepted Answer

Certain noncitizens should consider the risks of flying, including on domestic flights within the US.

On an average day, approximately three million passengers take domestic flights within the US. Many of these passengers are noncitizens, the vast majority of whom complete their travel without incident.

However, from the start of President Trump's second term through February 2026, Immigration and Customs Enforcement (ICE) arrested over 800 people at airports. A broad range of noncitizens have been targeted for immigration arrests, including people with no prior arrest history, people currently authorized to remain in the US due to a pending immigration application, and people who hold a temporary or discretionary status such as DACA, TPS, or parole.

ICE is using flight passenger information provided by the Transportation Security Administration (TSA) to locate non-citizens it chooses to target, and to arrest them when boarding or after disembarking from flights.

Based on reports, certain noncitizens may face more particular risk of arrest, including:

people who lack authorization to be in the US
people who have a final order of removal
people with an expired visa, even when the person has filed an application to extend or change their visa status, or where the person has filed another type of immigration application
people who held a temporary lawful status that has expired or that the government has revoked, including people who entered the US under parole, or who held Temporary Protected Status (TPS)
people with Deferred Action, including those granted Deferred Action for Certain Childhood Arrivals (DACA)
people with any prior criminal arrest

The above is not a complete list of noncitizens who have been arrested or who may be at risk of arrest. In its quest to detain and deport more people, ICE may further broaden its list of targets over time.

Noncitizens who feel uncertain regarding their own risks should consult an attorney, if able to do so.

If you are questioned at the airport by ICE or any other law enforcement agency, you have rights. Learn more here.

Question 2

What types of law enforcement officers could I encounter when entering or leaving the United States?

Accepted Answer

When traveling, you may encounter agents from several parts of the Department of Homeland Security. These include the Transportation Security Administration (TSA), Immigration and Customs Enforcement (ICE), and Homeland Security Investigations (HSI), which is part of ICE. At the border or when entering the US at international airports, you are also likely to encounter Customs and Border Protection (CBP) officers.

Question 3

If I am entering the U.S. with valid travel papers, can law enforcement officers stop and search me?

Accepted Answer

Generally, customs officers may stop people at the airports and/or the border to determine whether they are admissible to the United States, and they may search people’s belongings for contraband. This is true even if there is nothing suspicious about you or your luggage. The government believes this authority to search without individualized suspicion extends to searches of electronic devices such as laptops and cell phones, but that is a contested legal issue. Officers may not select you for a personal search or secondary inspection based on your religion, race, national origin, gender, ethnicity, or political beliefs.

Question 4

Can border officers ask questions about my immigration status?

Accepted Answer

Customs officers have the authority to ask your immigration status in order to determine whether you have the right to enter the country. If you are a U.S. citizen, you need only answer questions establishing your identity and citizenship, although refusing to answer routine questions about the nature and purpose of your travel could result in delay and/or further inspection. If you are a lawful permanent resident (LPR) who has maintained your status, you only have to answer questions establishing your identity and permanent residency. Refusal to answer other questions will likely cause delay, but officials may not deny you entry into the United States for failure to answer other questions. If you are a non-citizen visa holder or visitor, you may be denied entry into the United States if you refuse to answer officers’ questions. Officers may not select you for questioning based on your religion, race, national origin, gender, ethnicity, or political beliefs. If you are told you cannot enter the country and you fear you might be persecuted or tortured if you are sent back to the country from which you traveled, you should tell the customs officer about your fear and ask for asylum.

Question 5

Can U.S. customs officers ask questions about my religious beliefs and practices or political opinions?

Accepted Answer

Religious and political beliefs and associations are protected by the First Amendment. Customs officers have sometimes asked travelers about their religious affiliation, religious practices, association with religious institutions, and political opinions. The travelers targeted for such questioning have often been Muslim. Questioning individuals about their religious and political beliefs, associations, and practices can infringe upon rights guaranteed by the Constitution and federal law — these rights are not surrendered at an airport or the border. If you are a U.S. citizen or lawful permanent resident who has maintained status, you do not have to answer questions about your religious beliefs and practices or political opinions, and you cannot be denied entry to the United States for declining to answer such questions. If customs officers persist in asking you such questions, you can request to see a supervisor. If you are a non-citizen visa holder or visitor, you may decline to answer general questions about your religious beliefs and political opinions, but doing so may lead to delay or additional questioning, or possibly denial of your entry into the country. If you are told you cannot enter the country and you fear you might be persecuted or tortured if you are sent back to the country from which you traveled, you should tell the customs officer about your fear and ask for asylum.

Question 6

Do I have to provide my fingerprints when entering the country?

Accepted Answer

All visitors and lawful permanent residents are fingerprinted on entry into the United States from abroad.

Question 7

If I am selected for a longer interview when I am coming into the United States, what can I do?

Accepted Answer

Your legal status in the country may inform what you decide to do if you are selected for longer questioning when entering the United States. U.S. citizens have the right to enter the United States, so if you are a U.S. citizen and the officers’ questions become intrusive, you can decline to answer those questions, but you should be aware that doing so may result in delay and/or further inspection. The same is true for lawful permanent residents who have maintained their status: you generally cannot be denied entry to the United States, but declining to answer questions may result in delay or further inspection. Refusal by non-citizen visa holders and visitors to answer questions may result in denial of entry.

If the officers’ questions become intrusive or improper, you can ask to speak to a supervisor or file a complaint after the fact. (This goes for citizens, lawful permanent residents, or non-citizen visa holders and visitors.) Although CBP takes the position that you are not entitled to an attorney during primary and secondary inspection, we encourage you to have the telephone number of an attorney or legal services organization with you and ask to contact them if you feel your rights are being violated or if you have been detained for an unusually long period. For anyone attempting to enter the United States, if a customs officer or border agent informs you that you are under arrest, or if it becomes clear that he or she suspects you have committed a crime, you can ask to speak to a lawyer before answering any further questions — and if you wish to exercise your right to remain silent, you should say so out loud.

Question 8

Do I have to provide my laptop passwords or unlock my mobile phone for law enforcement officers at the border?

Accepted Answer

Customs officers have sometimes asked travelers to provide their laptop passwords or unlock their mobile phones when they are entering or leaving the United States. Your legal status in the country may inform what you decide to do if you’re asked for a password to unlock your device. U.S. citizens cannot be denied entry to the United States for refusing to provide passwords or unlocking devices. Refusal to do so might lead to delay, additional questioning, and/or officers seizing your device for further inspection. The same should be true for those who have previously been admitted to the U.S. as lawful permanent residents and have maintained their status — their green cards can’t be revoked without a hearing before an immigration judge. Visa holders and tourists from visa waiver countries, however, run the risk of being denied entry if they refuse to provide a password, and they should consider that risk before deciding how to proceed. If an officer searches and/or confiscates your laptop or cell phone, get a receipt for your property.

Question 9

What if I am selected for a strip search at the border?

Accepted Answer

A strip search at the border is not a routine search. It must be supported by “reasonable suspicion” and must be done in a private area.

Question 10

What types of law enforcement officers and other government officials could I encounter during the security screening process at the airport?

Accepted Answer

At airports, Transportation Security Administration (TSA) officers conduct security screenings. Most TSA officers are not commissioned law enforcement officers, and their role is to conduct screening of passengers, baggage and cargo. TSA screeners can search you and your baggage at screening checkpoints, but they cannot arrest you. Other law enforcement officers, such as airport police, are present at airports.

Question 11

Can my bags or I be searched after going through metal detectors with no problem or after security sees that my bags do not contain a weapon?

Accepted Answer

Yes. Even if the initial screening of your bags by TSA reveals nothing suspicious, the screeners have the authority to conduct a further search of you or your bags. Screeners may not select you for a personal search or secondary inspection based on your religion, race, national origin, gender, ethnicity, or political beliefs.

Question 12

What if I wear a religious head covering and I am selected by airport security officials for additional screening?

Accepted Answer

You have the right to wear your religious head covering. You should assert your right to wear your religious head covering if asked to remove it before going through airport security screening. If an alarm goes off, however, airport security officers may request additional screening. They may then conduct a pat-down of your religious head covering or ask you to remove it. You have the right to request that the pat-down or removal be conducted by a person of your gender and that it occurs in a private area.

If you do not want the TSA officer to touch your religious head covering, you must refuse and say that you would prefer to pat down your own religious head covering. You will then be taken aside, and a TSA officer will supervise you as you pat down your religious head covering. After the pat-down, the TSA officer may rub your hands with a small cotton cloth and place it in a machine to test for chemical residue. If you pass this chemical residue test, you should be allowed to proceed to your flight. If the TSA officer insists on the removal of your religious head covering, you have a right to ask that it be done in a private area. Officers may not conduct additional screening based solely on your race, national origin, religion, gender, ethnicity, or political beliefs.

Question 13

What if I am traveling with children?

Accepted Answer

You may opt your children out of an airport scan. However, there is no exemption for children from the pat-down search. Children under 13 years old may leave their shoes, light jackets, and headwear on during screening.

Question 14

What if I am traveling with breast milk or formula?

Accepted Answer

Parents and caregivers flying with and without children are permitted to bring breast milk and formula (and ice packs or other accessories required to cool the breast milk or formula) in quantities greater than three ounces, as long as you notify the officers about the items at the security checkpoint. When carrying breast milk or formula through the checkpoint, they will be inspected. TSA officials may test the liquids for explosives. TSA officials may ask you to open the containers during the screening process. Breast milk and formula, along with other liquids and gels, may also be packed in your luggage and checked with your airline.

Question 15

If I am on an airplane, can an airline employee interrogate me or ask me to get off the plane?

Accepted Answer

An airline pilot may refuse to fly a passenger if s/he reasonably believes, based on observation, that the passenger is a threat to flight safety. A pilot may not, however, question you or refuse to allow you on a flight because of biased stereotypes, including any based on your religion, race, national origin, gender, ethnicity, or political beliefs.

Question 16

What do I do if I am questioned by law enforcement officers every time I travel by air and I believe I am on a “no-fly” or other “national security” list?

Accepted Answer

If you believe you are mistakenly on a list, you should contact the TSA and file an inquiry using the Traveler Redress Inquiry Program. More information is available here. If you think there may be some reason for why you have been placed on a list, you should seek the advice of an attorney.
