Visa Rejection

Hi everyone,
I’m looking for experiences from anyone who has been in a similar situation.
My bachelor’s is in Biology and my master’s is in Chemistry. I have been admitted to the WHU Master’s in International Business for the September 2026 intake.
My first German student visa application was refused because the embassy was not convinced that my transition from science to business was academically and professionally justified.
For my second application, I submitted a much stronger Letter of Motivation explaining:
why I want to move into business,
how it connects to the healthcare/life sciences industry,
and my long-term career goals.
Has anyone here been approved after reapplying following a refusal for a similar reason?
I’d appreciate hearing about your experience or any advice.
Thanks!
