college and fulltime status question

Our daughter will be turning 19. She is on our insurance from work but only until the end of the month if she is not considered a fulltime student. She goes to a community college, but is not taking the required 12 credits to be considered fulltime by the registrar because with her LD (CAPD, dyslexia, etc) she has to work so hard now I can't imagine what it would be like with a full load The disabilities office gave her a letter saying they considered her full time with 9 credits but the registrar is balking on verifying her as fulltime. Has anyone else run into this? We need it resolved within 2 weeks or she will lose insurance coverage
Thanks
