Quick summary
Visa Waiver Program nationals flying to Micronesia need a US ESTA whenever the itinerary touches Guam or Honolulu, and the scheduled routings to Pohnpei, Chuuk, Yap and Kosrae connect through one of them. The fee is US$40.27 per person and rises to US$40.62 on 16 October 2026. Apply only at esta.cbp.dhs.gov or the official ESTA Mobile app.
The authorization lasts two years or until the passport expires, whichever comes first, and it is not a visa — it only gets you on the aircraft. Micronesia then applies its own visa-free stay: 90 days in any 180 for most EU passports.
The US ESTA fee rises from US$40.27 to US$40.62 on 16 October 2026, three days from today. Anyone who files before then pays the lower figure.
The cost reaches beyond a US holiday. The Federated States of Micronesia is a sovereign country with its own visa rules. But flights to its four states — Yap, Chuuk, Pohnpei and Kosrae — connect through Guam or Honolulu. For Visa Waiver Program nationals, that routing makes US authorization part of a trip to Micronesia.
So the answer to the question Europeans keep asking — do I need an ESTA for Micronesia? — is yes, whenever the routing touches US soil, a rule unchanged as of 13 October 2026.
Your Micronesia route may touch US territory
Micronesia runs its own immigration service, visa policy and arrival forms. It has no direct flight from Europe, North America or Australia.
The UK Foreign Office’s US travel advice states that ESTA applies to all air and sea travel to the United States, transit included. Guam and Honolulu are both US points of entry. A connection there counts as US entry, not a sterile airside transfer. The same rule applies to a two-hour connection at any US hub.
Without an approved ESTA, a Visa Waiver Program passport holder cannot board a US-bound flight, whatever the final destination. The arrival process is separate: how a Guam connection is cleared covers the forms and timing once you land.
Superdeals cover departures from North America, Europe and Australia.

What the ESTA costs and how long it lasts
The fee increase is set out in the Federal Register notice setting this year’s inflation adjustment. Before September 2025 the fee was US$21, so the same authorization has roughly doubled in price in thirteen months.
The charge has two parts. A processing fee of US$10.27 becomes US$10.62 on 16 October. Another US$30 is charged only if the application is approved. Payment is by Mastercard, Visa, American Express, Discover or PayPal.
A passport renewal means a fresh application and a fresh fee.
The official form takes about 23 minutes to complete, and most decisions arrive within minutes. But CBP publishes no guaranteed processing time, and some applications stay pending.
Who qualifies for ESTA — and who is blocked
ESTA is open to citizens of the Visa Waiver Program countries: 41 of them, including the UK, France, Germany, the Netherlands, Australia and New Zealand. Qatar is the newest member, with Qataris able to apply since 21 November 2024.
One group is blocked regardless of passport. Anyone who has visited Iran, Iraq, North Korea, Syria, Libya, Somalia or Yemen since March 2011 is ineligible, a rule set out on CBP’s Visa Waiver Program pages. One trip to any of those seven countries since that date closes the ESTA route. There is no workaround: the alternative is a US visa.
Romania shows how fast the list can change. Its Visa Waiver Program participation was announced in January 2025 and cancelled on 2 May 2025, so Romanian passports still need a visa rather than an ESTA. For a nationality outside the programme, neither the fee nor application timing changes eligibility.
Micronesia’s own entry rules by passport
Micronesia’s rules are separate from ESTA and, for most European passports, more generous. EU member states except Ireland, plus Iceland, Liechtenstein, Norway and Switzerland, get a 90-day visa exemption within any 180-day period, according to the FSM’s published visa policy.
The general category is 30 days, extendable to 60 days on request. The FSM also requires a passport valid for at least 120 days before arrival.
Travellers from the United States, the Marshall Islands and Palau fall into a separate 365-day group under Micronesia’s compact arrangements. The Visa Waiver Program rules do not affect those arrangements.
Departure taxes are collected when you leave each island. Cards are not accepted, and there are no ATMs at the airports.
Health and immigration paperwork before you fly
Health requirements sit outside both ESTA and the visa question. A yellow fever vaccination certificate is required if you arrive from a country where yellow fever is a risk; the rule follows the route, not the passport. Proof of COVID-19 vaccination is no longer required for entry to the FSM. That change took effect on 28 July 2023.
On the customs side, travellers may need to declare cash or equivalent instruments of US$10,000 or more on entry. The FSM uses the US dollar, so there is no currency conversion to plan for.
Measles vaccination is recommended following the 2019 outbreak. An international vaccination certificate may also be requested from travellers arriving from regions with smallpox, yellow fever or cholera.
Where the rules change by departure point
The Micronesia end of the trip differs by passport, and North America splits in two.
North America. US passport holders need no ESTA and enter Micronesia visa-free under the Compact of Free Association, per the US State Department. Canadian passports are not in the Visa Waiver Program, so ESTA is not available to them at all; Canada sits in Micronesia’s 30-day group.
Europe, including the UK. UK, French, German and Dutch passports all qualify for the US authorization. On the Micronesia side, Ireland and the UK fall into the 30-day group rather than the longer exemption available to most EU passports.
Australia and New Zealand. Both are Visa Waiver Program members. Both are in Micronesia’s 30-day visa-free group, with the same passport validity requirement as everyone else.
Apply before the 16 October fee change
Apply only at esta.cbp.dhs.gov or in the official ESTA Mobile app. Filing when you book, rather than the week you fly, is the cheap insurance.
- Check the passport first — renew before applying if the expiry date falls inside your travel window.
- Confirm the routing — if the itinerary does not touch Guam or Honolulu, the US authorization is not the document you need.
- Line up the FSM paperwork — the Immigration and Departure Control Registration Form 5004 is required on arrival, and departure taxes are cash only, so carry small US dollar notes.
- Watch: the 16 October 2026 fee change and your passport expiry date — the two dates that decide whether you pay once or twice.
Confirm the current health requirements with FSM immigration or your airline before departure. These are the rules most likely to shift between booking and flying.
The order is passport, then ESTA, then the Micronesian arrival forms. After the fee change, nothing else about the process changes: line up the paperwork before departure.

Questions? Answers.
Does ESTA apply if I don’t leave the airport in Guam?
Yes. ESTA covers all air and sea travel to the United States, transit included, so a connection at Guam or Honolulu counts as entry even if you never leave the terminal.
Can I apply for ESTA at the airport?
No. Applications are accepted only online at esta.cbp.dhs.gov or through the official ESTA Mobile app. The official form takes about 23 minutes, and while most decisions arrive within minutes, CBP publishes no guaranteed processing time.
Which countries are not eligible for ESTA?
Nationals of countries outside the Visa Waiver Program cannot use ESTA at all; Canada, for example, is not a member. Within the programme, anyone who has visited Iran, Iraq, North Korea, Syria, Libya, Somalia or Yemen since March 2011 is also blocked.
Are there direct flights from Europe to Micronesia that avoid US territory?
Not on scheduled service. The FSM’s four states are reached by connecting flights that route through Guam or Honolulu, both US points of entry, so the ESTA question does not disappear by changing carriers.
What happens if my passport expires while my ESTA is still valid?
The authorization ends when the passport does, even if the two-year period has not run out. Because ESTA is tied to the passport number, a renewal means a new application and a new fee: US$40.27 now, US$40.62 from 16 October 2026.
