Supplementary schools in Northamptonshire may be forced to close when their funding is withdrawn next year.
The schools, run by volunteers at weekends, teach pupils from different backgrounds about their culture and life in the UK.
Twenty schools in the county received council funding, but this money will be cut from March 2012.
The council said it was working with schools to find funding alternatives.
Around 2,000 pupils attend these schools, including those from Polish, Chinese, Arabic communities.
Dahlia Panayis, from the Northampton Greek school, said: "We already have a lot fundraising that we do throughout the year and it still isn't enough.
"The cost of the classrooms alone would be difficult to keep going."
The county council said it announced the cut in funding two years ago.
David Mackintosh, from the council, said: "We are offering the Supplementary Schools Association a chance to talk to directly with head teachers."
A meeting has been set up by the county council with the schools forum next week.
