There are plenty of schools but the quality of training is dubious at best. The prices they charge are also fairly astronomical. Expect to spend between S$3-5k per year.
Offically you can apply for a student pass to study at these schools. SIR is however usually very stingy with such passes as this is NOT the type of foreign talent they are trying to cultivate. As they are in it for the money, the schools don't tell you this and usually just shrug their shoulders when the student pass gets rejected. You might get better luck if your friend has some kind of family roots in Singapore.
