Entry requirements for Guam
🇨🇦 Canadian passport holders
Read the full Canadian entry requirements
Guam is a territory of the United States.
Some countries have imposed measures in response to the Ebola disease outbreak. These can include restrictions on entry and health screening measures for travellers having recently visited an affected country. If you are suspected of having symptoms, you may be subject to isolation, quarantine and/or travel restrictions. Contact the authorities of the country you are travelling to for more details.
The authorities of a country or territory decide who can enter or exit through its borders. The Government of Canada cannot intervene on your behalf if you do not meet your destination’s entry or exit requirements.
We have obtained the information on this page from local authorities. It can, however, change at any time.
Verify this information with the Foreign Representatives in Canada.
Passports
Entry requirements vary depending on the type of passport you're travelling with.
Before you travel, check with your transportation company about passport requirements. Its rules on passport validity may be more stringent than the country's entry rules.
Regular Canadian passport
Your passport must be valid for the duration of your stay in Guam.
Passport for official travel
Different entry rules may apply.
Passport with “X” gender identifier
While the Government of Canada issues passports with an “X” gender identifier, it cannot guarantee your entry or transit through other countries. You might face entry restrictions in countries that do not recognize the “X” gender identifier. Before you leave, verify this information with the closest foreign representative for your destination.
You should also be aware that current systems used by some countries and travel companies may not recognize the “X” gender identifier. You may still be asked to provide your sex/gender information as either male or female when travelling.
Other travel documents
Different entry rules may apply when travelling with a temporary passport or an emergency travel document. Before you leave, verify this information with the closest foreign representative for your destination.

Other passports
Rules depend on your nationality, so we do not guess. Before you book:
- Read your own government's travel advice first.
- Not sure what your passport needs? Check the visa rules for your nationality (eVisas visa checker) or compare with VisaHQ. These are affiliate links: if you use their application service we may earn a commission at no extra cost to you. Official government sites are usually cheaper and are linked above where we have them.
- Check your passport: many countries want it valid for 6 months after arrival and with blank pages.
- Check for an e-visa, travel authorisation or digital arrival card, and any vaccine rules (yellow fever is the common one).
- Ask your airline: they can refuse boarding if your documents do not match the rules.
Entry rules are set by each government and change without notice. This summary is for planning only and is not legal or immigration advice. Confirm on the official government website and with your airline before you book or travel. Voyaggora is not a government agency and does not process visas.
