Legal analysis: divorce in the United States is divided into simple divorce procedure and ordinary divorce procedure. Ordinary divorce procedure, the procedure starts from the date when the applicant files a lawsuit and serves a summons on the other party. After a six-month observation period, the court will announce the divorce.

Legal basis: Article 206 of the United States Uniform Marriage and Divorce Act. The court and authorized government officials can preside over the wedding, or they can hold the wedding in accordance with religious ceremonies. Unlike China's laws, in the United States, marriage certificates in different states are valid, which is similar to that in the United States. That is, the validity of marriage certificates ranges from 30 days to 60 days. During this period, both men and women must hold a wedding, otherwise they must re-register for marriage. In addition, both men and women have to wait for a waiting period of 3-5 days to apply for registration, which is finally issued by the court or the government.
