Residence Permit and Student Visa Conflict

Hello,

I'm currently an overseas student who is planning on undertaking exchange in China next year in February, but I hope to have a family holiday in January first. Last year, when I visited my family in China, I applied for the 5-year family reunion residence in hopes of making my future visits smoother and less restricted.

However, I have recently learned that in my exchange program, I must have entered the country with a X1 or X2 visa.

As such, I am wondering:

1. Would it be possible for me to apply for a X2 visa without cancelling the residence permit? (Either in China or out)

2. If not, do I have to leave China in January to first cancel the residence permit and also apply for a X1/X2?

3. Would it be possible to change my family reunion one to a student one in China in January with my admission letter?

As I only JUST got the family reunion residence permit, it'd be a shame if I have to cancel it so soon and waste all the money spent. Who should I contact regarding this issue? My local Chinese embassy? The Chinese university? I'm not sure if anyone would be able to give me an exemption.

Thank you for your help!
