Hundreds of children without parents are coming to Britain every year to try and escape danger in their own countries.
They come to Britain because it is a much safer place to live and ask for something called political asylum, which will let them live in the country.
Not everyone is given asylum and if they don't get it they are sent back to the country that they came from.
A decade ago just 1% of asylum seekers were unaccompanied children but now that figure has shot up to 20%.
Not enough foster home spaces
When the children arrive they are supposed to stay in foster homes, but there aren't enough foster homes so they have to spend time in shared houses or bed-and-breakfasts.
The charity Save the Children say around 3,000 children under the age of 18 come to Britain every year.
