long term study - best options?

[Springbokke]

Hi there

Can anyone advise a beginner Mandarin learner who is intent on dedicating three years to learning the language in China what the best option is in terms of schooling.

I have read through scores of threads but it is not clear whether long term programs are more drawn out, or are more comprehensive, or both?

I am all for immersion, but I have read mixed reviews of the homestay option - is it possible to immerse yourself without staying with a Chinese family in Beijing?

Please help

Thanks
