Urgent tuition assistance needed — final-year university student in China I’m a Bangladeshi Computer Science student completing my final year at Nanjing University of Posts and Telecommunications. After losing my scholarship, I’ve been working to cover my living expenses, but I still owe ¥15,000 (approximately $2,100) in university tuition. My residence permit expires on November 20, 2026. I’m trying to secure the tuition by November 18 so I can continue my education. I’ve contacted several organizations but haven’t secured financial assistance. Any donation, however small, would help. I can provide redacted university documents to verify my situation. Donate or share my fundraiser: https://whydonate.com/fundraising/help-me-finish-my-final-year-in-china Thank you for reading and considering my request. @mutualaid @mutualaid@fedigroups.social @mutualaidspace@mutualaidspace.org @disability @disability@fedigroups.social @wrzky @wrzky@kolektiva.social #disability #DisabilityCrowdfund #disabilitymutualaid #EmergencyCrowdfund #fedihelp #fediverse #healthcare #mentalhealth #mutualaid #mutualaidrequest #socialmedia #fedigive #mutualaidspace #politics #poverty #solidarity #internationalism #tuitionfee #tuitionfeeassistance #scholarship #education #CompSci #techactivism #activism
