Ahmad Mulakhil, 23, was convicted of two counts of raping a child under 13 in Nuneaton, central England, last July after a trial at Warwick Crown Court.
He had previously pleaded guilty to a further count of rape and was also found guilty of abducting a child, two counts of sexual assault and making indecent images of a child.
Jurors at a 10-day trial were told that Mulakhil arrived in the United Kingdom four months before the rapes and had made an immigration application linked to "problems" he had experienced in Afghanistan.
His co-defendant Mohammad Kabir, 24, was found not guilty of attempting to take a child, committing an offence with intent to commit a sexual offence and intentional strangulation in connection with an earlier encounter with the victim on the same day.
The trial was not told that Mulakhil arrived in the UK by small boat or that Kabir had entered the UK by the same method on Christmas Day in 2024.
Anti-immigration activists have seized on other criminal cases involving asylum seekers, predominantly young men and particularly those housed in hotels, to argue that they are a danger to nearby communities.
Pro-migrant groups, however, have said ultranationalist groups and opportunistic politicians are deliberately seeking to exploit and inflame tensions for their own ends.
Prosecutor Daniel Oscroft told jurors at the start of Mulakhil's trial last month that Mulakhil had led the victim to a "secluded cul-de-sac ... where he raped her, sexually assaulted her and took indecent images of her".
Remanding Mulakhil in custody to be sentenced at a later date, judge Kristina Montgomery said of him: "He will plainly receive a substantial custodial sentence which will automatically make him liable for deportation at its conclusion."
Commenting after the case, a UK Home Office spokesperson said: "We will not allow foreign criminals and illegal migrants to exploit our laws. We are reforming human rights laws and replacing the broken appeals system so we can scale up deportations."
