Essential Facts for Visiting guam
Right then, for our mates from the UK heading to Guam for a bit of a holiday, you'll be chuffed to know that generally, you won't need a traditional visa for short tourist or business stays, thanks to the US Visa Waiver Program (VWP). Guam, being a US territory, falls under these rules, so it's not quite the faff of applying for a full visa.
However, and this is absolutely key, you *must* have an approved Electronic System for Travel Authorization (ESTA) before you even think about boarding your flight. Without it, you'll be in a spot of bother at check-in, as it's a mandatory pre-screening for VWP travellers. Make sure it's sorted well in advance of your trip, eh?

Your passport needs to be proper valid, mind. For UK citizens travelling to Guam under the Visa Waiver Program, your passport must be an e-Passport (one with the chip symbol on the front cover) and it needs to be valid for at least six months beyond your intended period of stay. If you're planning a two-week jolly, make sure it's got at least six months and two weeks left on it from your arrival date.
It's always a good shout to double-check your passport's expiry date well before you book your flights. An invalid passport could lead to a right kerfuffle at the airport, and nobody wants that when they're looking forward to some sunshine. Ensure it's in good nick and meets all the VWP requirements.

Even if you're just nipping through Guam on your way to another destination, perhaps for a quick stopover, the same entry requirements generally apply. Since Guam is US territory, you'll still need an approved ESTA if you're a UK citizen travelling under the Visa Waiver Program, even if you don't plan to leave the airport.
Don't get caught out thinking transit is different; it's treated as entering US jurisdiction. So, to avoid any unnecessary faff or a bit of a bind, ensure your ESTA is sorted before you travel, regardless of whether Guam is your final stop or just a brief layover. Better safe than sorry, eh?

For UK citizens, your travel authorization status for Guam is absolutely essential: you need an approved Electronic System for Travel Authorization (ESTA). This isn't just a suggestion; it's a mandatory requirement for anyone travelling under the Visa Waiver Program, which is how most UK tourists visit US territories like Guam.
Think of it as your digital green light to enter. Applying for an ESTA is a no-brainer and should be done at least 72 hours before you travel, though many recommend doing it much earlier to avoid any last-minute panic. Once approved, it's generally valid for two years or until your passport expires, whichever comes first.

Health & Safety Tips for guam
For any immediate emergencies in Guam, including police, fire, or medical assistance, dial 911. This is the universal emergency number, consistent with the mainland United States, and operators are equipped to dispatch the necessary services promptly. It's crucial to remain calm, clearly state your location, and describe the nature of your emergency.
When contacting emergency services, providing clear and concise information about your exact location is paramount, especially if you are in a less familiar area. Street names, nearby landmarks, or even GPS coordinates from a smartphone can be incredibly helpful for responders to reach you quickly. English is widely spoken by emergency dispatchers, ensuring effective communication for international tourists.
Beyond 911 for critical situations, it's advisable to have non-emergency contact numbers handy, such as your hotel's front desk, your tour operator, or your country's embassy or consulate in the region (if applicable, often located in nearby Manila or Tokyo, or specific consular services for U.S. citizens). Familiarizing yourself with these numbers before your trip can provide an extra layer of preparedness for less urgent matters.

Guam, being a tropical island, requires visitors to take general health precautions. Staying well-hydrated is crucial due to the warm climate, and consistent use of high-SPF sunscreen is recommended to prevent severe sunburn. Be mindful of potential vector-borne diseases like dengue fever; while risk varies, using insect repellent, especially during dawn and dusk, is a wise preventive measure.
Food and water safety in Guam is generally good, but travelers should exercise caution with street food or unbottled water if unsure of its source to prevent gastrointestinal issues. When enjoying Guam's beautiful beaches and waters, be aware of marine life hazards such as jellyfish or sharp coral, and always heed warnings about strong currents or rip tides. Swim only in designated areas and never alone.
It is always recommended that international tourists check the latest health advisories issued by their home country's health authorities (e.g., CDC for U.S. citizens) or the World Health Organization (WHO) prior to travel. These resources provide up-to-date information on any specific health concerns, outbreaks, or recommended precautions relevant to Guam at the time of your visit.

For most international travelers, there are generally no mandatory vaccination requirements for entry into Guam. As a U.S. territory, Guam's entry requirements for vaccinations largely align with those of the mainland United States, primarily focusing on routine immunizations rather than specific travel-related vaccines unless you are arriving from an area with a high risk of certain diseases, such as Yellow Fever.
Despite the lack of mandatory entry vaccinations, it is strongly advised that all travelers are up-to-date on their routine vaccinations. This includes standard immunizations like Measles, Mumps, Rubella (MMR), Diphtheria-Tetanus-Pertussis (DTaP), Varicella (chickenpox), Polio, and your annual flu shot. Consulting with your healthcare provider at least 4-6 weeks before your trip is essential to review your immunization history and discuss personal health risks.
Depending on your travel style and planned activities, your doctor might also recommend specific vaccines such as Hepatitis A and B, and Typhoid, especially if you plan to consume food and beverages outside of major tourist resorts or engage in activities that could expose you to local water sources. Always refer to the latest guidelines from your national health agency or the CDC for personalized recommendations.

Tipping in Guam is customary and follows practices similar to those in the mainland United States. In restaurants and bars, a tip of 15-20% of the bill is expected for good service, as it forms a significant part of service workers' income. For other services, such as hotel bellhops, housekeepers, taxi drivers, or tour guides, a few dollars per service or a percentage of the total fare is a standard and appreciated gesture of gratitude for good service.
