First, verify that your bachelor’s degree meets the academic requirements of your chosen program. Next, prepare your language test scores and required documents. Applications are usually submitted online through the university’s official portal or through Uni-Assist, depending on the program. After receiving your admission letter, you must arrange financial proof through a blocked account of approximately €11,000–€12,000 per year, apply for a German student visa, secure accommodation in Heidelberg, and complete enrollment before the semester begins.
