People who were already working in real life usually had to meet some special requirements and conditions if they wanted to go to a formal full-time university. First, they had to meet the university's admission requirements, including age, education, work experience, and so on. Some universities may accept work experience as one of the conditions for admission, but the specific requirements vary from school to school and major. Secondly, they needed to have sufficient financial support. Colleges usually had to pay tuition fees, living expenses, and so on, so they needed to prove that they had enough financial ability to bear these expenses. Finally, they needed to provide a valid identification and recommendation letter. These certificates can help the university understand the true situation of the applicants and assess their learning ability and potential. Although there are some circumstances that may allow people who are already working to attend full-time university, under normal circumstances, these requirements and conditions may impose some restrictions on the applicants. Therefore, applicants are advised to consult the University Admissions Office to understand the admission requirements and application process and prepare the required materials and proof.
