Threatening of cancellation of student visa/resident permit in Zhenjiang, china
A friend of mine who is a PhD student in Zhenjiang, Jiansu was not satisfied with the way his meager monthly stipend (1,000 rmb) was always paid. Monthly stipend had turned to quarterly payment. In the admission letter, it was monthly but in reality, before they could be paid this small 1,000 rmb, sometimes , its after 2 or 3 or 4 months. so he decided to deceive the school by filling application leave to his country for winter holiday (Jan 16 to Feb., 25, 2019). Now the school is threatening to cancel his residency if he cant resume after March 5, 2019. He is actually in another city in Jiangsu working as English teacher and he planned to do this for 5 months before his visa expires and travel back home.
Can the school cancel the resident permit even though they don't have his passport (hard copy) with them. Wouldnt he ran into trouble when leaving china in next 4 months?
