AM A YONG MAN FROM NIGERIA. I APPLIED FOR STUDENT VISA AT CHINEESE EMBERSSY IN LAGOS AND I WAS CALLED FOR INTERVIEW AFTER THE CONFERMATION FROM THE SCHOOL (CHINA UNIVERSITY OF MINNE AND TECHNOLOGY). I DID THE INTERVIEW ON 12TH MARCH, 2010 AND I WAS GIVEN A PICK UP SLIP. BUT TO MY SUPRISE, I WAS GIVEN ONLY MY PASSPORT WITHOUT VISA ON MY PIC UP DATE (19TH MARCH, 2010).THE BADEST PART OF IT WAS THAT, ALL MY DOCCUMENTS WERE WITHOLD AND NO REASON WAS GIVEN FOR ALL THIS ACTION. PLEASE, TELL ME WHAT TO DO BECAUSE, I AM CONFUSED.
