Legal analysis: when college students go to college, boys can get married at the age of 22 and girls can get married at the age of 20. To register for marriage and get a marriage certificate, you must reach the legal age for marriage, which refers to the minimum age for marriage stipulated by law, but there is no limit to the maximum age for marriage. Therefore, men and women who have reached the legal age of marriage during their college years can apply for marriage registration in person with relevant documents and materials. Upon examination, those who meet the conditions for marriage shall be granted registration and a marriage certificate shall be issued.

Legal basis: Article 1047 of the Civil Code of People's Republic of China (PRC) stipulates that the age of marriage shall not be earlier than 22 for men and 20 for women.
