Ministers are facing calls to start processing Syrian asylum applications again, as new figures showed more than 7,000 people are still in limbo.
The UK paused decisions on Syrian claims for asylum and permanent settlement in December, after the fall of President Bashar al-Assad.
But more than five months on, Syrians in the UK still do not know when their claims will be assessed.
Charities including the Refugee Council say the current situation has left people in an "indefinite limbo" and are calling for claims to be processed again on a case-by-case basis.
The government said decisions were paused "while we assess the current situation".
A Home Office source said this was "a necessary step while there is no stable, objective information available to make robust assessments of risk" on people returning to Syria and the policy "will remain under constant review".
A total of 7,386 Syrians were waiting for an initial decision on an asylum claim by the end of March, according to the latest figures published on Thursday.
Assad's regime was overthrown by a rebel offensive led by the Islamist militant group Hayat Tahrir al-Sham (HTS) in December, after years of civil war.
HTS leader Ahmad al-Sharaa was named as Syria's interim president earlier this year, but the situation remains uncertain and HTS is still designated a terrorist group by the UK.
In December, the Conservatives suggested most Syrian asylum claims were related to the threat posed by Assad's government and those people could return when it was safe to do so.
However, Haytham Alhamwi, chairman of the Syrian British Consortium, said while many Syrians left because of Assad's rule others may still feel unsafe to return.
"Many of them are still calling for democratic change in Syria, which is not guaranteed at the moment. Some of them were afraid of those military groups, they didn't come running from Assad himself," he told the BBC.
The number of Syrian asylum claims fell by 81% following the UK's decision to pause decisions.
However, despite a sharp drop, 299 Syrians came to the UK on small boats in the first three months of this year – 5% of the total number of arrivals.
