Here is what you need to know about certificates of application and exercising your rights whilst your EUSS application is processed 


The Withdrawal Agreement provides protection to all those who have made valid applications to the EUSS, including those who have reasonable grounds for applying late. Therefore, late EUSS applicants will also be issued with certificate of application by the Home Office once their application has been validated (i.e. once the Home Office has assessed the reason(s) for missing the deadline and accepted that the late application is justified). This means that those who have missed the deadline for good reason still have the right to work, study and to access NHS etc, whilst they are waiting for the Home Office to issue a decision. Therefore, organisations and government departments should accept your certificate of application as proof of your rights whilst you are waiting for a decision, even if you applied late.

Unfortunately, travelling on a certificate of application is a complicated area, as the Home Office applies different policies depending on the situation of the EUSS applicant. It is therefore very important to read this information carefully if you are planning to travel outside the UK before the outcome of your EUSS application. 

  • EU citizen resident by 31 December 2020 with a valid in-time EUSS application: You should be entitled to enter the UK using your certificate of application by itself, unless Border Force has doubts about you being resident by 31 December 2020 and / or there are doubts whether you have maintained continuous residence. If your EUSS application has been refused and you have a pending out of country appeal, then you may be required to show Border Force evidence that you were resident by 31 December 2020 and you have maintained continuous residence.
  • Non-EU citizen family member resident by 31 December 2020 with a valid in time EUSS application and a document issued under the EEA Regulations (‘valid’ or expired): You should be entitled to enter the UK if your EUSS application is based on the same family relationship that you were issued a document under the EEA Regulations for. This is unless Border Force has doubts about you being resident by 31 December 2020 and / or there are doubts whether you have maintained continuous residence. If your EUSS application has been refused and you have a pending out of country appeal, then you may be required to show Border Force evidence that you were resident by 31 December 2020 and you have maintained continuous residence.
  • Non-EU citizen family member resident by 31 December 2020 with a valid in time EUSS application but no document issued under the EEA Regulations: You should be entitled to enter the UK if you can show Border Force evidence that you were resident by 31 December 2020, that you have maintained continuous residence and your family relationship is accepted. This includes if your EUSS application has been refused and you have a pending administrative review or out of country appeal. 
  • EU citizen resident by 31 December 2020 with a valid late EUSS application: You should be entitled to enter the UK if you can show Border Force evidence that you were resident by 31 December 2020 and you have maintained continuous residence. This includes if your EUSS application has been refused and you have a pending administrative review or out of country appeal. 
  • Non-EU citizen family member resident by 31 December 2020 with a valid late EUSS application: You should be entitled to enter the UK if you can show Border Force evidence that you were resident by 31 December 2020, that you have maintained continuous residence and your family relationship is accepted. This includes if your EUSS application has been refused and you have a pending administrative review or out of country appeal. 
  • EU citizen or family member with a refused in-time or late EUSS application who has made an in-country appeal that is pending with the Immigration Tribunal: you should be entitled to enter if you can show Border Force you have a pending appeal, as long as you are not entering the UK via a “juxtaposed port” (these are Eurostar and ferry terminals in France and Belgium). If you are entering via a juxtaposed port, then you will need to show evidence that you were resident by 31 December 2020 and you have maintained continuous residence (and your eligible family relationship if applicable). 
  • Joining family member with an EUSS Family Permit: You should be entitled to enter the UK if you were granted an EUSS Family Permit (either valid or expired) before you applied to the EUSS. However, if your family permit is expired and your EUSS application has been refused, you may not be permitted entry even if there is a pending administrative review or out of country appeal.  
  • Joining family member without an EUSS Family Permit: You will likely be refused entry to the UK. However, if your EUSS application has been refused and you have an in-country appeal pending against this decision, you can enter the UK as long as you are not entering the UK via a “juxtaposed port”. 

Note that Border force always has a discretionary power to admit a person to enter the UK, if compelling or compassionate circumstances apply. Compelling or compassionate circumstances are not defined as each individual situation will be assessed by Border Force. Examples given in the Border Force guidance are decisions that affect children or vulnerable adults with specific care or support needs. Therefore, although the above situations summarise the general approach, Border Force can allow entry even if the general policy conditions are not met. 

As can be seen, Border Force policy is very complicated and means that persons with certificates of application need to be very careful if they plan to leave the UK temporarily, or travel to the UK having applied to the EUSS from outside the UK. Despite Home Office policy allowing some certificate of application holders to re-enter the UK, the general advice from the Home Office is not to travel until the EUSS application is decided. 

Yes, it does have an impact, as carriers (this means airlines, Eurostar or ferry operators) need to check all persons travelling to the UK have permission from the Home Office before allowing them to “board” (travel to the UK). There are different permissions to travel to the UK which includes Electronic Travel Authorisation (ETA) for non-visa visitors, or immigration status such as pre-settled or settled status held by long term UK residents. Carriers only need to check the passenger has a Home Office permission to travel to the UK, the carrier is not responsible for checking if the permission held by the passenger is the ‘correct’ permission covering the reason the person wants to the enter the UK, as checking the permission is correct is the job of Border Force at the UK border (e.g. Border Force will check if travellers holding an ETA are genuinely visiting, as only persons visiting the UK are permitted to travel with an ETA). 

“…enforcement under the carriers’ liability scheme is not yet in effect. At this stage, carriers are not expected to deny boarding to a passenger of ETA-eligible nationality solely because they do not hold an ETA. We are aiming to begin enforcement of ETA in 2026, and we will ensure further information and sufficient notice is provided to carriers, key stakeholders and CoA holders before this.”

This means that non-visa nationals (which includes all EU citizens), should be allowed to travel to the UK on certificates of application (though remember entering the UK at the border is determined by Border Force policy set out above). This page will be updated to reflect any change in Home Office policy for 2026 once this information is known. 

“Visa nationals who have a valid pending application to the EU Settlement Scheme are advised not to travel to the UK until their application is granted unless they hold a valid visa or visa exemption document. A Certificate of Application or Acknowledgement of Application is not satisfactory evidence of status.”

If you hold an EUSS Family Permit this is an acceptable document for carriers to accept. However, carriers are very unlikely to accept an EUSS Family Permit that has expired.
