Due to others issues and you pass 5th september 2016 before applying for x1 visa.does it expire?

I am a young man selected to Wuhan university but am in south africa and am from sierra leone They told me to go back home to apply for study X1 or get 6months validity permit in south africa. I have all documents and less validity days in south africa. i didnt know they will need 6months permit to apply for X1. Am afraid its late for me to gather other expense to my country because its too expensive .i kept it for my tuition but i have no choice but travel or make my 6months permit here In order to be elligible to apply while in SA. Is my admission and jw202 be valid if i pass 5sept before applying for my study X1? will they consider me? Or what must i do? Will they need me to apply again? Am confused . help. my country is far. i have all necessary documents only that my permit in SA doesnt have 6months remaining in it. Thanks
