Visa or Electronic Travel Authorisation (ETA) guidance for Users

If you are a non-UK user you may need a visa or an ETA to visit the UK.

If you are from the EU, the current rules state that you are allowed to travel to the UK for six months or less without needing a visa. For any travel after 2 April 2025, you will need to apply for an ETA.  

If you are non-UK/EU, you may need a visa or an ETA to visit the UK – please check here to see if you will need to apply for a Standard Visitor visa or please check here to see if you will need to apply for an Electronic Travel Authorisation. The UK has added 49 new countries to the list of nationalities who require an ETA for travel from 8 January 2025 so we advise you to check this list.

A Standard Visitor visa allows you to undertake certain business activities such as attending a meeting or conference or to gather information for your employment overseas and if you are a scientist, researcher or academic you can carry out research or collaborate in the UK. You cannot do paid or unpaid work for Diamond (including work placements and internships).

A Standard Visitor visa allows you to stay for a maximum of six months per visit. For further information please see the official guidance here.

Diamond has taken the decision to suspend its work with Russian and Belarusian affiliated institutions, including suspending access for users from those institutions, until further notice.

Science has always been about bringing people together beyond all boundaries, promoting scientific excellence and peace. We stand with all those who seek peace amid this crisis and beyond.

We would like to advise that we cannot allow work on new samples that involve collaboration with Russian/Belarusian institutions. For data that has already been collected publication with these authors is up to PI, but we would ask that it is made clear that this is not recent beam time, by explicitly stating when the beam time was.
