Sir Mo Farah said he is "relieved" he can travel back to his family in the US after British dual nationals were given exemption from Donald Trump's travel ban to the country.
In response to the news, the Somalian-born British athlete's agent released a statement saying he was "grateful to the FCO for urgently clarifying the situation."
"Mo is relieved that he will be able to return to his family once his current training camp concludes, however, as he said in his earlier statement, he still fundamentally disagrees with this incredibly divisive and discriminatory policy," he said.
British Olympic champion Sir Mo Farah has said Donald Trump's travel ban is "deeply troubling".
The Somalia-born four-time Olympic champion could be affected by the ban, which targets those from Iraq, Iran, Libya, Somalia, Sudan, Syria and Yemen, and could affect UK citizens born abroad.
In a statement, Sir Mo Farah, who was born in Somalia, said:
On 1st January this year, Her Majesty The Queen made me a Knight of the Realm. On 27th January, President Donald Trump seems to have made me an alien.
I am a British citizen who has lived in America for the past six years - working hard, contributing to society, paying my taxes and bringing up our four children in the place they now call home.
Now, me and many others like me are being told that we may not be welcome.
It's deeply troubling that I will have to tell my children that daddy might not be able to come home - to explain why the president has introduced a policy that comes from a place of ignorance and prejudice.
I was welcomed into Britain from Somalia at eight-years-old and given the chance to succeed and realise my dreams.
I have been proud to represent my country, win medals for the British people and receive the greatest honour of a knighthood.
My story is an example of what can happen when you follow polices of compassion and understanding, not hate and isolation.
Sir Mo grew up in London from the age of eight and now lives and trains in Portland, Oregon, with his wife and four children.
The athlete's agent said although he was born in Somalia, he does not have dual nationality or hold a Somalian passport. She added: "We are seeking to clarify the situation with the US authorities."

Mo Farah talked medals, children, and the joy of the Olympics during an interview on Sunday, after successfully winning the 'double double'.
"I never dreamed of becoming an Olympic champion four times," he said. "It's been a long journey, but... there's no really words to describe."
He spoke of how difficult it is to be away from his children for so long - he has relocated to Portland in Oregon so that he can train with Alberto Salazar, long-distance running guru.
"Each one of my kids has one of these medals, so that's what drives me," he said. "If I stop today, at least they got something for the time I missed spending time with my kids."
