Key changes to UKVI guidance in 2026: what they mean for immigration DNA testing

For many families, an immigration application or appeal is one of the most important and stressful processes they will ever navigate.

In 2026, the landscape of UK immigration is changing significantly. UK Visas and Immigration (UKVI) is in the midst of its most ambitious modernisation programme to date, replacing physical immigration documents with a fully digital system and introducing new requirements for travellers and applicants alike.

Crucially, as the system places greater weight on verified, formal documentation, the role of DNA evidence in supporting immigration applications and appeals has never been more significant.

Where official documents are unavailable, incomplete, or insufficient, an accredited DNA test can provide the clear, reliable proof of biological relationship that UKVI and HM Passport Office require.

Here, we explain the key changes to UKVI guidance in 2026, what they mean in practice, and how immigration DNA testing can play a vital role in supporting applications and appeals when other evidence falls short.

The move to eVisas – what’s changing

What is an eVisa?

An eVisa is a digital record of a person’s immigration status, accessed through an online UKVI account. It replaces physical documents as the primary means of proving the right to live, work, or study in the UK.

What’s changing, and when?

UKVI has been issuing eVisas since 2018, but 2026 marks a decisive shift towards digital-only status:

• As of January 2026, most people granted a visit visa now receive an eVisa in addition to, or instead of, a visa sticker
• As of February 2026, visitor visas are issued exclusively as eVisas; physical visa vignettes are no longer provided for new applications
• Later in 2026, UKVI will stop issuing visa stickers entirely; all successful applicants will receive an eVisa only
• People who previously held a Form for Affixing a Visa (FAV), or who were granted a visa extension without a valid identity document, can now also create a UKVI account to access their eVisa

What does this mean for visa holders?

A UKVI online account is becoming essential, not optional.

Anyone holding an eVisa must ensure that their passport number and personal details are kept up to date in their account. If a traveller presents a passport that is not linked to their digital status, carriers may be unable to verify their permission to travel.

For immigration professionals, this means:

• reviewing all ongoing cases that rely on physical documents
• advising clients to set up and verify their UKVI accounts and
• ensuring that any change of passport is promptly reflected in the client’s digital record.

Electronic Travel Authorisation (ETA) – what you need to know

As of February 2026, the UK’s Electronic Travel Authorisation (ETA) requirement is now strictly enforced.

This affects millions of travellers from countries that were previously able to visit the UK without any advance permission, and it represents a fundamental shift in how the UK manages pre-travel security screening.

What is an ETA?

An ETA is a digital travel authorisation that must be obtained before travelling to the UK. It is linked electronically to the traveller’s passport and is checked by carriers before boarding.

Who needs an ETA?

The ETA requirement applies to nationals of approximately 85 countries that were previously able to visit the UK without a visa.

The following people do not require an ETA:

• British citizens and Irish citizens (who must travel on a British or Irish passport)
• Those who already hold a valid UK visa or eVisa
• Those with settled or pre-settled status under the EU Settlement Scheme

To check whether an ETA is required, individuals can use the UK Government’s official visa checker tool.

What are the practical implications?

As of February 2026, carriers are legally required to refuse boarding to passengers who need an ETA but don’t have one.

For immigration professionals, this means ensuring that any client travelling to the UK has obtained the correct pre-travel authorisation in advance, particularly where a client may be unfamiliar with the new requirements. Failure to do so risks significant disruption to travel plans and, in some cases, could affect the timing of an immigration application or appeal.

What these changes mean for immigration applications and appeals

A higher evidential bar

As UKVI moves towards a fully digital immigration system, the standards applied to supporting documentation are becoming more rigorous. Applications that rely on incomplete, inconsistent, or unverifiable evidence are at greater risk of refusal.

This is particularly relevant for family visa applications and appeals, where applicants must demonstrate a genuine biological relationship to a UK sponsor or citizen.

Under the Immigration Rules, applicants are ordinarily expected to provide documentary evidence of their relationship, such as birth certificates, marriage certificates, or adoption records.

However, there are many circumstances in which such documents are simply not available, cannot be verified, or are not accepted as sufficient by a UKVI caseworker.

These include situations where:

• Official records were never issued, have been lost, or were destroyed
• Documents originate from countries where record-keeping standards vary significantly
• The authenticity of submitted documents is questioned by the caseworker
• An application has previously been refused and is now subject to appeal
• A child was born abroad to a UK citizen parent, and parentage needs to be formally confirmed

In each of these scenarios, the absence of reliable documentary evidence does not have to mean the end of an application.

It is in precisely these circumstances that DNA testing can play an important role.

The voluntary nature of DNA evidence

It is important to note that the submission of DNA evidence in support of an immigration application is entirely voluntary.

The Home Office does not have the power to require an applicant to undergo DNA testing, and any invitation to provide DNA evidence must make it clear that this is one of a range of options available.

However, where an applicant independently chooses to submit DNA evidence, and that evidence is produced in accordance with Home Office collection standards by a UKAS 17025-accredited laboratory, it can carry significant weight with caseworkers and, where relevant, immigration tribunals.

When is DNA testing useful for immigration applications?

DNA testing is a well-established and powerful tool for verifying biological relationships, and it can prove invaluable in a wide range of immigration scenarios.

Some of the most common situations in which an applicant or their legal representative might consider submitting DNA evidence in support of an immigration application or appeal include:

• A child born abroad to a UK citizen parent: where a parent is seeking citizenship or a passport for a child born outside the UK, a paternity or maternity DNA test can confirm the biological relationship between parent and child, supporting the application where birth registration documents are unavailable or insufficient.
• Family reunion applications: where a UK resident is sponsoring a relative’s application to join them in the UK, and documentary evidence of the relationship is incomplete or questioned by a caseworker, DNA testing can confirm the biological relationship between the sponsor and the applicant.
• Applications involving extended family relationships: not all immigration cases involve straightforward parent-and-child relationships. In some cases, it may be necessary to confirm a relationship between siblings, grandparents and grandchildren, or aunts/uncles and nieces/nephews, particularly where a direct parental link cannot be established.
• Passport applications: where a person is applying for a British passport on the basis of a familial relationship with a British citizen, and supporting documents are unavailable, DNA evidence can be submitted to HM Passport Office to confirm that relationship.
• Appeals following refusal: where an initial application has been refused, in part due to insufficient evidence of a biological relationship, DNA testing can provide the additional, objective evidence needed to support an appeal.

Which DNA relationship tests are available for immigration cases?

AlphaBiolabs offers a comprehensive range of DNA relationship tests that can be used to support immigration, visa, and passport applications. These include:

• Paternity testing: to confirm whether a man is the biological father of a child
• Maternity testing: to confirm whether a woman is the biological mother of a child
• Sibling DNA testing: to determine whether two individuals share one or both biological parents
• Grandparent DNA testing: to assess the likelihood of a grandparent-grandchild relationship
• Aunt/uncle (avuncular) DNA testing: to determine whether an individual is the biological aunt or uncle of a child
• Y chromosome testing: to confirm a relationship between males sharing the same paternal line
• Extended family testing: including cousin relationships, where no closer relative is available for testing

Our in-house team of expert geneticists can advise on the most appropriate test for each individual case, based on the specific relationships involved and the evidence already available.

How immigration DNA testing works

For DNA evidence to be accepted by UKVI, the Home Office, HM Passport Office, or an immigration tribunal, it must be produced in accordance with strict collection and laboratory standards.

Understanding these requirements is essential for anyone considering DNA testing in support of an immigration application or appeal.

Accreditation requirements

The Home Office requires that any DNA testing submitted in support of an immigration or passport application is performed by a laboratory accredited to the international quality standard ISO/IEC 17025 by the United Kingdom Accreditation Service (UKAS).

This accreditation confirms that the laboratory operates to the highest standards of scientific rigour, quality management, and accuracy.

Choosing a non-accredited laboratory risks the DNA evidence being rejected outright by UKVI or HM Passport Office, regardless of the quality of the result.

A list of Home Office-approved laboratories – including AlphaBiolabs – can be found on the GOV.UK website.

Chain of custody sample collection

For DNA evidence to be admissible in support of an immigration application, samples must be collected under strict chain of custody conditions. This means:

• Samples are collected by a trained, independent sample collector – not by the individuals being tested
• Each donor must provide photographic identification at the point of sample collection, to confirm that samples are taken from the correct individuals
• Donors must provide consent for their samples to be used for DNA testing; for children under 16, consent must be provided by a parent or guardian with parental responsibility
• The collection process is fully documented, ensuring a clear and unbroken record from sample collection through to laboratory analysis and reporting

It’s important to note that where photographic ID cannot be provided at the point of collection – for example, in cases involving asylum seekers or refugees who may not be in possession of identity documents – there is a risk that the DNA evidence may not be accepted by the Home Office.

In these circumstances, it is advisable to seek guidance from a specialist immigration solicitor before proceeding.

Sample collection in the UK and abroad

One of the practical challenges of immigration DNA testing is that the individuals being tested are frequently located in different countries.

In a typical case, a UK-based sponsor may need to provide a DNA sample in the UK, while a relative living abroad provides their sample at an overseas location.

AlphaBiolabs is experienced in managing exactly these situations. Our international sample collection network operates across more than 90 countries worldwide, working closely with immigration centres, consulates, and embassies to ensure that samples are collected efficiently and in full compliance with Home Office requirements.

For samples collected abroad, a sample collection kit is sent to the required overseas location, and an appointment is arranged via a local GP, medical practice, hospital, or other approved clinic.

Samples collected both in the UK and abroad are processed under full chain of custody, with photographic identification obtained from each donor.

What happens in the laboratory?

Once samples arrive at the laboratory, geneticists extract DNA from the cheek cell samples and analyse up to 45 DNA markers – double the industry standard – to determine whether the individuals being tested share a biological relationship.

The results are then reported clearly and objectively, in a format that is accepted by UKVI, the Home Office, HM Passport Office, Border Force, Immigration Enforcement, and UK courts.
