If foreign interns are offered a job, they have to change their visa type from internship to employment, otherwise they will be suspected of staying illegally in the country or being illegally employed, Lin said.
Cao said about 30 percent of interns are hired by the Chinese companies where they worked.
Meng Ling, a partner with Perfect Alliance CPA Partnership, a Shanghai accounting firm, said they have hired foreign interns ever since they opened for business in 2006.
Meng said the company currently has two foreign interns working as audit assistants, one from Singapore, the other from Britain.
"Foreign interns not only bring different cultures, they're also helpful in improving English communication in the office," he said. "We're impressed by their patience and carefulness, which is quite important for our work. And our staff members can learn those good qualities from them."
Meng said companies like his, whose clients are mainly foreign enterprises, always hire foreign interns.
Gu Lili, a manager with International Students Travel Exchange in Beijing, said they expect the numbers of foreign interns in China to continue to rise. Last year the company helped more than 100 students intern in China.
"As China sustains a quick economic growth and Western markets weaken, and Chinese enterprises become more open to the outside world, more foreigners will seek internships in China," she said.
Gu said one of the recruitment projects her company is promoting is a beer festival at a tourism resort in Beijing scheduled in August, which needs some 20 foreign interns to work as receptionists and waiters.
