Entry requirements for the United Kingdom

ESC Congress 2024 London, 30 August - 2 September

Information provided as of November 2023

IMPORTANT - National ID cards are no longer accepted for travel. A valid passport is required.

NEW - Electronic Travel Authorisation (ETA)

From November 2023, the UK Government has started to introduce an ETA (Electronic Travel Authorisation). The scheme is broadly for visitors who do not need a visa for short stays to the UK, or do not already have a UK immigration status prior to travelling. It will eventually be required by anyone entering the UK apart from those with:

  • A British or Irish passport
  • Permission to live, work or study in the UK
  • A visa to enter the UK

The ETA scheme is open to Qatari nationals, who can now apply and will require an ETA to travel to the UK on or after 15 November 2023. Other nationalities do not need to apply yet.

  • From 15 November 2023 – nationals of Qatar
  • From 22 February 2024 – nationals of Bahrain / Jordan / Kuwait / Oman / Saudi Arabia / UAE. These nationalities will be able to apply from 1 February 2024
  • If you are a national of another country, you do not need an ETA at this stage, however you might require a visa. Visit to find out more.
Process, Validity and Fees

Simply apply via the ETA App or
A decision is usually made within three working days.

The ETA is linked to your passport and lasts two years or up to the expiration date of your passport, whichever comes first.

The cost of an ETA is £10 per person, including for babies and children.

Not all visitors to the UK require a visa, however we strongly advise you find out if you need a visa to enter the UK as early as possible, and should a visa be required, to apply as soon as possible as the process can take up to 20 working days.


The following link will tell you if a visa is needed and explain the process

You’ll need to have your fingerprints and photograph (known as ‘biometric information’) taken at a visa application centre (VAC – see below) as part of your application. The application will not be submitted until that process has been completed. You will be able to book an appointment to provide your biometric information at the end of the online application.

Find details of your nearest visa application centre using this link:

For countries where there is no visa application centre, you may find a Temporary Enrolment Location is available on given days or you may need to travel to a nearby country where a visa application centre is available.  Should you live in a country where no visa application centre is available you should take account of additional timescales for biometric submission when considering when to apply.

In support of your application, you should gather evidence of your circumstances, employment, ability to meet the costs of the trip and the arrangements in the UK. More details can be found via this link to the guide to supporting documents.

If you have already registered for the congress, we would strongly recommend that you include a copy of the registration confirmation letter (email) together with the congress invitation letter to these documents.

You can request an invitation letter from the ESC using the button below:

(You will be requested to create a My ESC account if you do not already have one)

Request an invitation letter

After you have submitted your request, you will receive an email with a link to download your invitation letter.

The letter is intended to help delegates raise travel funds or obtain a visa but does not imply the ESC will provide financial support.

In case of a visa request rejection, the ESC will refund the full registration fee only upon receipt of the official refusal document from the Embassy.


Visitors from Australia, Canada, Japan, New Zealand, Singapore, South Korea and the United States of America will now be able to use e-gates upon arrival in the UK.

Frequently Asked Questions related to UK Visa

  • How much does it cost to apply for a Standard visa?
    As of October 2023, the cost for a Standard visa is £115 per person.
  • When should I apply for my visa and how long will my application take? 
    The process can take up to 20 working days from submitting biometrics, but we recommend that applications are made as early as possible, from up to 3 months before the congress and allowing at least four weeks. In many locations, for an additional fee, delegates may be able to use our Priority and Super Priority visa service.
  • I am applying late – what is a Priority and Super Priority Service?
    Priority service means that the UK Visa and Immigration office will aim to make a decision on your application in 5 working days, this service is available in over 200 locations. Super Priority service reduces this to the end of the next working day, this service is available in around 20 locations. Both services are charged at an additional fee. Some applications may take longer if they are complex, please check the visa application centres website for any further information.
    Fees - Fees for Priority and Super Priority Services apply in addition to the Standard visa fee, as follows: £500 for Priority and £1,000 for Super Priority.
    Important note: Priority service does not imply or guarantee in any way that a delegate will be 
    successful in their visa application. All visa applicants must meet the requirements of the UK immigration rules.
  • I travel a lot and cannot be without my passport, are there any services that could help?
    The UKVI offer a Keep My Passport service in over 40 locations, this allows the applicant to keep their passport while their application is being considered. If their visa application is successful they will need to provide their passport to the VAC for the vignette to be printed. This service comes at an additional cost and details of which services are available at each VAC are available on the  commercial Partner website.
  • What travel date should be stated on the application form? 
    On the application you should be specific in stating planned dates of travel to and from the UK. Visitors cannot arrive in the UK earlier than the start date on their visa and the airline may not let you board their flight, or they may be refused entry on arrival in the UK. It is not usually possible to make changes to the validity dates of a visa, after it has been printed. If plans change, you may need to make a new visa application.
  • What can I do if my visa is refused? 
    A decision to refuse a visa is made only after careful consideration of all the facts by an Entry Clearance Officer, including the fact that the delegate is to attend or contribute to a specific event. If the application is refused, the refusal notice will provide details about the reasons for refusal. Visitors are free to make a new application, but it is strongly recommended that they read their refusal letter carefully and fully address all the reasons for the initial refusal.
