Home Secretary Priti Patel has announced changes to the Ukrainian visa scheme after it came under fire.
Ms Patel was criticised that the scheme forced red tape against the thousands of people fleeing for their lives from Russian attack in Ukraine.
Speaking in the House of Commons this morning (March 10), she promised to 'streamline' the online visa application system.

She defended the changes by saying that Ukrainians with passports will be able to apply for a visa online, which will free up appointments at the visa application centre for those who don't have passports.
Ms Patel told MPs the changes will come in from Tuesday following assurances from the security services that the UK can still be protected from Russian efforts to infiltrate the country by posing as Ukrainian refugees.
The Home Office has come under pressure from opposition and Tory MPs - as well as the Ukrainian government - to simplify the system which allows family members of people settled in the UK to join their relatives.
Ms Patel said: "From Tuesday, I can announce that Ukrainians with passports will no longer need to go to a visa application centre to give their biometrics before they come to the UK.
"Instead, once their application has been considered and appropriate checks completed, they will receive direct notification that they're eligible for the scheme and can come to the UK.
"In short, Ukrainians with passports will be able to get permission to come here fully online from wherever they are and will be able to give their biometrics once in Britain.
"This will mean that visa application centres across Europe can focus their efforts on helping Ukrainians without passports."
More than two million people have fled Ukraine since Russia's invasion.
While the European Union allows visa-free travel for Ukrainians fleeing the fighting, the UK insisted they are necessary to guarantee security.
Ms Patel argued that the checks, visas and need for digital and paper documentation will give refugees a record of their status and give them rights to benefits and right to work in the UK.
She told the Commons: "I am in daily contact with the intelligence and security agencies who are providing me with regular threat assessments.
"What happened in Salisbury showed what (Russian President Vladimir) Putin is willing to do on our soil. It also demonstrated that a small number of people with evil intentions can wreak havoc on our streets."
Ms Patel said she was able to change the visa regime following security agencies' fresh advice.
Yvette Cooper, Shadow Home Secretary criticised the Home Secretary, saying that she had weeks and months to prepare, calling the Home Office's approach "shameful".
The current visa route is restricted to family members of people settled in the UK.
Another promised route - allowing individuals and companies to sponsor Ukrainians to come to the UK - has not yet been established.
Ms Cooper said: "Is this still just being restricted to those with family? Are they still going to have to fill in multiple online forms, or would she now say that all those who want to come to the UK who have fled the fighting in Ukraine can now come here without having to fill in loads of online forms or jump through a whole load of hoops?
"This has just been shameful, making vulnerable people push from pillar to post in their hour of need - week after week we have seen this happen.
"It is deeply wrong to leave people in this terrible state. Our country is better than this. If she can't get this sorted out, frankly she should hand the job over to somebody else who can."
Figures from Downing Street on Wednesday showed Britain has granted just 957 visas.
Ukrainians have faced a series of bureaucratic hurdles and difficulties in obtaining appointments to complete the necessary paperwork.
Armed forces minister James Heappey said British troops could assist in processing claims.
Ukrainian ambassador to the UK Vadym Prystaiko called for an end to the "bureaucratic red tape" restricting refugees from seeking sanctuary in Britain.
He told BBC's Question Time: "I just wanted to tell you that most of our men are staying behind and fighting, so ... most of the people you will see are just women with children, which I totally hope they're not posing any threat, especially a terrorist threat to the UK.
"So that's why I hope and I beg that the procedures will be dropped and every bureaucratic red tape should be cancelled."
Education Secretary Nadhim Zahawi said plans were under way in his department to take "100,000 children ... into our schools".
