Navigating travel to the United States requires understanding potential safety and security risks. This guide provides a detailed overview of America Travel Warnings, offering essential information to ensure a safe and informed trip. Whether you’re planning a visit to bustling urban centers or exploring the vast natural landscapes, being aware of potential hazards and taking necessary precautions is crucial for a smooth and secure travel experience. This comprehensive resource covers everything from border safety and crime concerns to health advisories and legal considerations, empowering you to travel with confidence across America.
Understanding Safety and Security in the United States
America, while generally safe for travel, presents various safety and security considerations that visitors should be aware of. From petty theft in tourist hotspots to potential risks in specific regions, understanding these warnings is the first step in ensuring your well-being.
Border Regions: Special Attention at the Mexican Border
Border regions, particularly those bordering Mexico, require increased vigilance due to criminal activities linked to drug trafficking. These incidents are more prevalent in states like California, Arizona, New Mexico, and Texas.
If you are driving across the U.S.–Mexico border:
- Exercise extreme caution at all times.
- Utilize only official, recognized border crossings.
- Avoid nighttime travel in these areas.
Crime: Navigating Petty and Violent Crime Risks
Crime in the U.S. ranges from petty theft to violent acts, with varying levels of risk depending on location and time of day.
Petty Crime: Protecting Yourself from Theft
Petty crime, including pickpocketing and purse snatching, is a concern, especially in crowded urban areas and popular tourist destinations.
- Never leave bags or valuable items unattended, particularly in parked vehicles, including rental cars, even if they are placed in the trunk.
- Keep your belongings secure at all times, including passports and travel documents. Consider using hotel safes or secure travel pouches.
Violent Crime: Staying Safe in Urban Areas
Violent crime is more frequent in impoverished neighborhoods within large cities, especially during the hours of dusk to dawn. While tourists are less likely to be direct targets, it’s essential to be aware of your surroundings. Incidents often involve intoxication and can be perpetrated by gangs, organized crime members, or individuals.
- Maintain situational awareness and be mindful of your surroundings at all times.
- Check official neighborhood crime statistics before venturing out, particularly in the evening. Resources like the FBI’s Crime Data Explorer can provide valuable information.
- If confronted by robbers, remain calm and do not resist. Your safety is paramount; material possessions can be replaced.
Gun Violence: Understanding the Risks
The United States has a high rate of firearm ownership, and in many states, open carry of firearms is legal. Mass shootings, unfortunately, occur and can result in casualties. While tourists are rarely directly involved, the risk of being caught in an active shooter situation exists.
- Familiarize yourself with active shooter response protocols. The Cybersecurity and Infrastructure Security Agency provides a helpful Active Shooter Event Quick Reference Guide. Knowing how to react – Run, Hide, Fight – can significantly increase your chances of survival.
Home Break-ins: Securing Vacation Rentals
Canadians and other visitors staying in holiday homes have been targets of break-ins and burglaries.
- Ensure all windows and doors are securely locked at night and whenever you leave the property. Consider using additional security measures like alarm systems if available.
Common Criminal Tactics: Recognizing and Avoiding Ploys
Be alert for robbery schemes specifically targeting tourists. Some criminals operate near airports and tourist areas, employing tactics to lure travelers into vulnerable situations. One common ploy involves criminals signaling to tourists that there is a problem with their vehicle, hoping they will pull over. Another tactic includes throwing objects at windshields to force drivers to stop.
- Avoid pulling over on the side of the road if someone signals you.
- Activate your hazard lights and slowly drive to a safe, populated location such as a gas station or police station.
Demonstrations and Civil Unrest
Demonstrations and protests can occur and sometimes escalate unexpectedly. Even peaceful gatherings can turn violent, leading to disruptions in traffic and public transportation.
- Avoid areas where demonstrations or large gatherings are taking place.
- Follow instructions from local authorities if you encounter a demonstration.
- Monitor local news and media for updates on planned or ongoing demonstrations.
Fraud and Financial Security
Credit card and ATM fraud, including debit card cloning, is a concern.
- Pay close attention when your cards are being handled by others, especially in restaurants and shops.
- Use ATMs located in well-lit public areas or inside banks or reputable businesses. Avoid stand-alone ATMs in dimly lit or isolated locations.
- Be wary of card readers with unusual or irregular features, which could indicate skimming devices.
- Shield the keypad with your hand when entering your PIN at ATMs and point-of-sale terminals.
- Regularly check your account statements for unauthorized transactions.
For more information on protecting yourself from fraud, consult resources on overseas fraud.
Terrorism: Maintaining Vigilance in Public Spaces
There is an ongoing threat of terrorism in the United States, and attacks could occur at any time. Potential targets include:
-
Government buildings, including schools and universities
-
Places of worship
-
Airports and transportation hubs
-
Public areas like tourist attractions, restaurants, shopping centers, and hotels
-
Always be aware of your surroundings in public places.
-
Pay attention to security alerts and public announcements.
-
The U.S. Department of Homeland Security (DHS) operates the National Terrorism Advisory System which provides public alerts about potential terrorist threats. Stay informed through official channels.
Hiking and Mountaineering Safety
For those planning outdoor adventures like hiking, backpacking, or skiing:
- Never engage in these activities alone. Always hire an experienced guide from a reputable company, especially in unfamiliar terrain.
- Purchase comprehensive travel insurance that includes helicopter rescue and medical evacuation coverage, particularly if venturing into remote areas.
- Obtain detailed information about hiking routes or ski slopes before setting out and strictly adhere to marked trails. Avoid venturing off-trail, as this can lead to getting lost or encountering unexpected hazards.
- Ensure you are in adequate physical condition for the planned activity. Acclimatize to higher altitudes gradually to prevent altitude sickness.
- Be properly equipped with appropriate gear, including navigation tools, communication devices, and weather-appropriate clothing.
- Stay informed about weather conditions and potential hazards. Mountain weather can change rapidly.
- Inform a family member or friend of your detailed itinerary, including expected return times.
- Learn to recognize the symptoms of acute altitude sickness, which can be life-threatening. Descend to a lower altitude immediately if symptoms appear.
Air Travel Safety Standards
It’s important to note that governments typically do not assess the compliance of foreign domestic airlines with international safety standards. Travelers should be aware of this when choosing domestic air carriers within the U.S. For more information, consult resources on foreign domestic airlines.
Entry and Exit Requirements for the United States
Entry and exit regulations are determined by each country. The responsibility for meeting these requirements rests solely with the traveler. The information provided here is based on data from U.S. authorities but is subject to change. Always verify the most current requirements with Foreign Representatives in Canada or the U.S. embassy or consulate in your country of origin.
Passport Requirements
Proof of citizenship is mandatory for entry into the U.S. for all travelers.
Air Travel Passport Requirements
For air travel to the United States, Canadian citizens must present one of the following:
- A valid passport, valid for the duration of your stay in the U.S.
- A valid NEXUS card, usable at designated airport kiosks.
These requirements are applicable to all Canadian citizens, including children, traveling to, or even transiting through, the United States by air.
Land and Water Travel Passport Requirements
Under the Western Hemisphere Travel Initiative (WHTI), for entry by land or water, Canadian citizens aged 16 and older must present:
- A valid passport
- A Trusted Traveler Program card (e.g., NEXUS, SENTRI, FAST)
- An Enhanced Driver’s License (EDL) or Enhanced Identification Card (EIC) from participating provinces/territories.

Additional Border Information
Customs officials may request your U.S. address, including for Puerto Rico. Customs and Border Protection (CBP) officers may also ask for:
- Evidence of residential, employment, or educational ties to your home country.
- Proof that your trip is for a legitimate purpose (tourism, business) and of a reasonable length.
- Proof of sufficient funds to cover your expenses during your stay.
Dual Citizenship Considerations
While U.S. authorities do not officially mandate dual nationals to carry both passports, carrying both your U.S. and Canadian (or other) passports can facilitate entry and exit processes.
Visa Requirements for the USA
Canadian visitors generally can stay in the U.S. for up to 6 months without a visa. You must declare your intended length of stay upon entry.
In most cases, visas are not required for Canadians for tourism, business, or transit from Canada. However, exceptions exist. Consult the U.S. Embassy & Consulates in Canada for specific details.
Visa Requirements for Permanent Residents
Canadian permanent residents may require a non-immigrant visa to enter the United States. This must be obtained from U.S. authorities before travel. A valid passport from your country of citizenship is also required. Refer to U.S. Customs and Border Protection for details.
Visa Waiver Program (VWP)
Citizens of countries in the Visa Waiver Program (VWP) can enter the U.S. for up to 90 days without a visa, but must obtain pre-travel authorization via the Electronic System for Travel Authorization (ESTA) prior to departure.
U.S. Permanent Residents
Canadians who are U.S. permanent residents must present a valid U.S. Permanent Resident Card (Green Card) upon entry. See U.S. Citizenship and Immigration Services for guidance.
First Nations and Native Americans
Members of Canada’s First Nations and Native Americans born in Canada have specific rights to enter the U.S. for employment, study, retirement, investment, or immigration purposes.
Working and Studying in the United States
Most Canadian business travelers can apply for admission at a U.S. port of entry without a visa. However, specific documentation might be required depending on the business category. For those planning to work in the U.S., contact the nearest U.S. embassy or consulate for detailed requirements.
Canadian citizens generally do not need visas to study in the U.S., but must be registered with the Student and Exchange Visitor Information System (SEVIS). Present your SEVIS registration form to CBP officers upon each entry.
Length of Stay and Extensions
For stays longer than 6 months, apply for an extension from U.S. Citizenship and Immigration Services (USCIS) within the U.S. before your authorized stay expires. Immigration officers may need proof that you are a temporary visitor.
Overstaying your authorized period can lead to serious consequences, including detention and deportation. While there’s no fixed waiting period for re-entry after an authorized stay, CBP officers may scrutinize frequent or lengthy stays to ensure you are genuinely a temporary visitor and not attempting to reside in the U.S.
Biometric Data Collection
Upon U.S. entry, non-U.S. citizens may be required to provide biometrics (digital fingerprints and photograph). Most Canadian citizens are exempt, but this may apply to those needing a visa or waiver of ineligibility, or those requiring an I-94 Arrival/Departure Record. Random screenings of exempt Canadians have occurred. Concerns about wrongful data collection can be addressed with the U.S. Department of Homeland Security.
Electronic Device Inspections at the Border
U.S. border agents have the authority to search electronic devices (phones, computers, tablets) upon entry. They are not obligated to provide a reason for requesting passwords. Refusal can lead to device seizure, travel delays, or denial of entry for non-U.S. citizens. Before crossing, enable airplane mode to prevent accidental downloading of remote files. See U.S. Customs and Border Protection guidance.
Preclearance in Canada
U.S. preclearance facilities in Canadian airports allow for U.S. entry processing before departure. You must meet U.S. entry requirements at these facilities and will be interviewed by a U.S. preclearance officer authorized to inspect luggage and deny entry. False statements to a preclearance officer are an offense under Canada’s Preclearance Act. You are subject to Canadian law within preclearance areas and can withdraw your request to enter the U.S. unless an officer suspects deception or obstruction, in which case detention under Canadian law is possible.
Criminal Record and Entry
A criminal record, regardless of severity or age, can lead to denied U.S. entry. Even a Canadian pardon is not recognized under U.S. law. If ineligible, apply for a temporary waiver of inadmissibility from U.S. Customs and Border Protection through a U.S. embassy or consulate, or at land borders. U.S. ports of entry are computerized with access to criminal databases. Past entries without issue do not guarantee future entry if a criminal record or prior denial is found. Attempting entry without a waiver can result in detention and a permanent U.S. entry ban.
Cannabis and U.S. Entry
Prior cannabis use, or any substance illegal under U.S. federal law, can result in U.S. entry denial. Attempting to enter for cannabis industry-related reasons may also lead to inadmissibility. Crossing the Canada-U.S. border with any amount of cannabis is illegal under U.S. federal law, even if traveling to a state where cannabis is legal, and can result in prosecution, fines, and potential jail time.
Boating in U.S. Waters
Operators of small pleasure vessels arriving from foreign ports must immediately report to U.S. Customs and Border Protection for face-to-face inspection at a designated reporting location, with some exceptions like Nexus Marine.
Cruises and Passport Requirements
A valid passport is mandatory for cruises departing from the U.S., and for re-entry into the U.S. at the cruise end. Some visited countries may also require passport entry. Ship authorities may retain passports during cruises for administrative and immigration clearance purposes. If your passport is held, obtain a receipt and ensure its return at the cruise end, and always carry a photocopy.
Pet Travel
Pets must appear healthy upon U.S. port of entry inspection. Evidence of poor health may lead to examination, testing (at owner’s expense), or entry denial. Additional requirements may include import permits, health/export certificates, and proof of vaccinations (e.g., rabies). Quarantine may be imposed.
Children Traveling in Groups
Canadian citizens under 19 traveling with school or organized groups under adult supervision must have written parental/guardian consent.
Yellow Fever and Entry
Refer to the health section for information on yellow fever vaccine entry requirements.

Safe Food and Water Practices
Many illnesses are food and waterborne.
- Follow safe food and water precautions to prevent illness. “Boil it, cook it, peel it, or leave it!”
- Avoid water contact with eyes, mouth, and nose when swimming in fresh water, especially after floods or heavy rain.
- Avoid inhaling or swallowing water while bathing or swimming in pools/hot tubs.
Insect Bite Prevention
Insect bites transmit diseases like Zika and Dengue.
- Use insect repellent on exposed skin.
- Wear light-colored, loose, tightly woven clothing.
- Minimize insect exposure, especially during peak biting times.
- Use mosquito netting when sleeping outdoors or in non-enclosed spaces.
Zika Virus: Zika is a risk in some U.S. areas, spread by mosquitoes and sexually. It poses risks for pregnant women, causing birth defects. Check the CDC’s Areas at Risk for Zika for current risk information. Prevent mosquito bites and practice safe sex during travel to Zika risk areas. Pregnant women should discuss risks with their healthcare provider and may consider postponing travel.
Dengue: Dengue risk is sporadic in the U.S., spread by mosquito bites. Dengue causes flu-like symptoms and can be severe. Risk levels vary seasonally and regionally. Dengue-carrying mosquitoes bite during the day, especially at sunrise/sunset. Protect against mosquito bites; there is no vaccine or medication for dengue fever.
Animal Precautions
Infections like rabies and avian influenza can be transmitted between animals and humans. Avoid contact with animals, including domestic and wild animals, and avoid undercooked wild game. Supervise children closely around animals.
Avian Influenza: Human cases of avian influenza have been reported in the U.S. Risk is low for most travelers. Avoid contact with birds (wild, farm, backyard, alive or dead) and surfaces contaminated by bird droppings. Ensure poultry and eggs are thoroughly cooked. High-risk travelers include those visiting live animal markets, poultry farms, or working with poultry or wild birds/mammals. Seasonal flu shots are recommended to protect against human influenza viruses.
Person-to-Person Infections
Stay home if sick and practice cough/sneeze etiquette. Reduce the risk of colds, flu, and other illnesses by:
- Frequent handwashing.
- Limiting time in crowded or enclosed spaces, and at large events.
- Avoiding close contact with symptomatic individuals.
Sexually Transmitted Infections (STIs), HIV, and mpox are spread through bodily fluids. Practice safe sex, use condoms, and limit sexual partners. Check with local health authorities about mpox vaccination eligibility.
Medical Services and Facilities

Medication Regulations
Importing certain prescription drugs into the U.S. is restricted or prohibited. Some over-the-counter Canadian medications require prescriptions in the U.S.
- Bring sufficient medication supplies.
- Have a physician’s note explaining your condition, if applicable.
Important Health Reminders
Travelers are solely responsible for their health and safety. Be prepared and do not expect Canadian healthcare standards. Pack a travel health kit, particularly when traveling outside major cities.
Laws and Culture in the USA
You are subject to local laws. Learn about procedures and assistance available if arrested or detained abroad. Laws vary significantly by state; consult state websites before traveling.
Penalties and Legal Consequences
Serious legal violations can result in jail sentences or even the death penalty in some states. Canadian citizenship offers no special legal protection. Jail sentences are served in U.S. prisons unless a transfer to a Canadian prison is approved by both countries under a treaty.
Drug Laws and Penalties
Penalties for drug possession, use, or trafficking are severe, including lengthy jail sentences and heavy fines.
Cannabis Laws
Despite cannabis legalization in some U.S. states, it remains federally illegal in any form or quantity. Transporting cannabis across the Canada-U.S. border is illegal and can lead to prosecution, fines, and jail time, even if traveling to a state where it is legal.
Prescription Medication Regulations
Personal medication may be subject to U.S. drug importation laws. Generally, a 90-day supply of personal medication is permitted. U.S. Customs and Border Protection has discretion over allowing Canadian-purchased medication into the U.S. When traveling with prescription medication:
- Bring only the quantity needed for your stay plus a week’s supply.
- Keep medication in original packaging with dispensary labels showing your name, drug name, dosage, and DIN.
- Carry a duplicate of your prescription, listing both generic and trade names.
- Have a physician’s note explaining your condition and need for syringes, if applicable.
Refer to U.S. Customs and Border Protection prohibited items.
2SLGBTQI+ Travelers
Some state laws and policies may affect 2SLGBTQI+ persons. Check state and local laws relevant to sexual orientation and gender identity. Consult resources on travel and 2SLGBTQI+ safety.
Dual Citizenship Considerations
Dual citizenship is legally recognized in the U.S. Consular services for dual U.S.-Canadian citizens may be limited in the U.S. and different entry/exit requirements may apply.
International Child Abduction
The Hague Convention on International Child Abduction applies between Canada and the U.S. If your child is wrongfully taken to or held in the U.S., act quickly, contact your province/territory’s Central Authority, seek legal counsel in both countries, and report to the nearest Canadian government office or Global Affairs Canada. Consular officials cannot intervene in private legal matters or foreign judicial affairs.
Expedited Removal Procedures
U.S. Customs and Border Protection can bar non-citizens from the U.S. for five years for presenting false documentation or misrepresentation. Lying to customs officials is a serious offense. There is no formal appeal process for expedited removal, but a supervisory review can be requested from U.S. Citizenship and Immigration Services.
Import and Export Regulations
Contact U.S. Customs and Border Protection at your planned Canada/U.S. border crossing for current information on import/export allowances and restrictions, as these frequently change. Declare all items at entry points.
Travel to Cuba from the USA
U.S. sanctions restrict tourist travel between the U.S. and Cuba. Travel from the U.S. to Cuba may be permitted under specific categories and requirements.
Driving Regulations
A valid Canadian driver’s license is accepted in the U.S. Traffic laws vary by state.
Automobile Insurance
Many states mandate auto insurance and proof of insurance. State motor vehicle departments provide specific details. For driving to Mexico from the U.S. in your vehicle, liability and additional auto insurance may be required.
Hitchhiking Risks
Never cross the border with or as a hitchhiker. You could be implicated in illegal activities. Be cautious about passengers and items in your vehicle, as the driver can be held responsible for passengers’ actions and belongings.
Currency and Finances
The U.S. dollar (USD) is the currency. Canadian currency and Canadian bank cheques are not widely accepted; most transactions require a U.S. bank account. There are no limits on money brought into or out of the U.S., but amounts exceeding US$10,000 (cash, cheques, money orders, etc.) must be declared to U.S. Customs and Border Protection upon entry or exit, or if received while in the U.S. Non-compliance can result in civil and criminal penalties, including currency seizure.
Natural Disasters and Climate Risks in America
Recent Natural Disasters
Los Angeles County Fires (January 2025 Example): (Note: Update with current relevant disaster information if available) Multiple fires in Southern California, including the Palisades Fire and Eaton Fire, caused casualties and property damage.
