Legal analysis: college students can pay social security, which has nothing to do with college graduates. Anyone who has reached the age of 16 can participate in social insurance, but college students are not employees of enterprises and cannot participate in the endowment insurance for urban employees. College students can only participate in flexible employment or residents' pension insurance. If you want to participate in the endowment insurance for urban workers, you must sign a labor contract with your unit after graduation, and you can only participate if you have labor relations.

Legal basis: Article 10 of the Social Insurance Law of People's Republic of China (PRC) * * * Employees shall participate in the basic old-age insurance, and both employers and employees shall pay the basic old-age insurance premium. Individual industrial and commercial households without employees, part-time employees who have not participated in the basic old-age insurance in the employer and other flexible employees can participate in the basic old-age insurance, and individuals pay the basic old-age insurance premium. The measures for the endowment insurance of civil servants and staff managed by reference to the Civil Service Law shall be formulated by the State Council.
