Ecuador's government says it will announce a decision on the fate of Julian Assange later today.
The WikiLeaks founder remains in the Ecuadorian Embassy in London where he is seeking asylum to avoid being sent to Sweden to answer accusations of sexual assault.
Mr Assange also faces arrest for breaching bail conditions.
The 40-year-old Australian has been inside the building, near Harrods in Knightsbridge, since Tuesday afternoon, when he requested political asylum under the United Nations Human Rights Declaration.
Ecuador's president, Rafael Correa, will make a decision on Mr Assange's application later, the country's deputy foreign minister Marco Albuja told the Australian Broadcasting Corporation.
The South American country, whose UK ambassador Anna Alban has met British officials, says Mr Assange is under its protection while it considers the application., which comes after his failed attempt to avoid extradition to Sweden under a European arrest warrant to face sex crime allegations.
The Foreign and Commonwealth Office (FCO) confirmed in a statement that he was "beyond the reach of the police" while he remains in the building.
Mr Assange faces arrest if he leaves the embassy.
The Metropolitan Police said Mr Assange had breached a condition of the £200,000 bail imposed by the High Court, that he stay at a bail address between 10pm and 8am.
Several high-profile figures have supported Mr Assange since his arrest in December 2010, including film director Ken Loach and socialite and charity fundraiser Jemima Khan, who each offered £20,000 as surety.
Ms Khan voiced her surprise at his move, writing on Twitter: "I had expected him to face the allegations. I am as surprised as anyone by this."
Mr Assange's move to claim asylum is the latest twist in a marathon legal battle played out in the glare of worldwide publicity.
He is set to be extradited to Sweden, where he faces accusations of raping a woman and sexually molesting and coercing another in Stockholm in August 2010 while on a visit to give a lecture.
Mr Assange, whose WikiLeaks website has published a mass of leaked diplomatic cables that embarrassed several governments and international businesses, says the sex was consensual and the allegations against him are politically motivated.
Last month, the Supreme Court upheld a High Court ruling made in November last year that his extradition was legal. Last week the same court refused an attempt by him to reopen his appeal against extradition, saying it was "without merit".
He had until June 28 to ask European judges in Strasbourg to consider his case and postpone extradition on the basis that he has not had a fair hearing from the UK courts.
