URGENT!!!!!!!!!!!

Hello,

I am Nigerian with X visa, I have got my residence permit and finished my 1 year course from a university. I'm currently studying in another city here in china with a private institution, we went to the bureau and was told my visa cannot be extended unless I have to travel back to my country to obtain F Visa meanwhile I still have 1 month residence permit valid.

I will like to renew my residence permit which my private institution is not capable of doing, I'm not willing to go back to Nigeria soon because I'm running a course here which is very important, I have got just 6 months left.

What do I need to do to extend my permit as soon as possible. I dont want to be illegal immigrant in china.

Suggestions are welcomed.

Thanks...
