'Child migrant' who said he was 16 when he came to the UK from the Calais Jungle boasts of being 22 on a dating website...

• Haris Stanikzai was among the first 14 children to arrive from the Jungle
• He told UK authorities he was 16 years of age but had no documentation 
• His LinkedIn profile claims he is in the third year of an accounting degree
• A profile on an internet dating website claimed Stanikzai was 22 years old

A child migrant who arrived in Britain last week has boasted on his online dating profile that he was 22 and has a LinkedIn profile where he claims he spent three years in university. 

Haris Stanikzai from Afghanistan told Home Office officials he was only 16 and arrived in London on October 17 to live with his uncle Jan Ghazi. 

However, several photographs posted on social media place doubts on his age, especially his LinkedIn profile which claims he has spent three years as a student in Jahan University in Kabul where he was studying accounting and finance.

Stanikzai was one of the first child migrants to arrive in Britain following the deal with French authorities after the Dubs amendment to fast-track the claims of unaccompanied minors. 

However, as soon as Stanikzai and his fellow migrants arrived, there was considerable controversy as many appeared to be far older than children. 

After his arrival in Britain,  Stanikzai, who arrived on Monday, said he was 16 – but he had been given an 'official' date of birth that makes him 17.

The Afghan youngster, who does not have a birth certificate, said the Home Office told him that he was born on January 1, 1999.

Haris told the Mail: 'I am 16 years old.' His uncle Jan Ghazi added: 'I do not know the exact day and month that he was born, but he is my nephew and I know, I can see, that he is 16.

'The Home Office may have said that his birth is on a particular date and I do not want to have an argument with them over it, but he is younger.'

If a refugee does not have a birth certificate, a Home Office screening officer can certify them as a child based on their 'physical appearance and demeanour'.

Unless the asylum seeker appears 'significantly' over 18, they should be 'afforded the benefit of the doubt and treated as children'.

When officials believe the refugee is a child but not the age they claim, screening officers will estimate a date of birth and write the word 'disputed' on their application form.

Last week, Stanikzai claimed in newspaper interviews that he was the last of his six siblings to survive the war in Afghanistan and the people smugglers.

According to the Sunday Times, Ghazi told the newspaper that his nephew must now report on a fortnightly basis to an immigration centre in South London, having been issued with a 'notification to a person who is liable to be detained'. 

French officials confirmed Britain has so far accepted almost 300 child migrants since they started to demolish the Jungle camp. 

The Home Office told MailOnline that they do not comment on individual cases. 

According to an agreement drawn up between French and British authorities, physical appearance and demeanour will be assessed to identify an individual's age in the absence of documentary evidence. 

In cases where there is no documentary evidence, but the individual is judged to be a minor, they will be assigned the date January 1 in the year of their birth on all offical documentation in accordance with UNHCR rules. 

If a migrant is found to be over the age of 18, they will be processed through the adult system. 

Under the current system, unaccompanied minors who do not qualify for asylum are granted leave to remain for 30 months - or until they reach 17 and a half if there is no 'safe and adequate' arrangements in their home country. 

However, these individuals can apply for 'leave to remain' which will be 'considered on a case-by-case basis'.
