INTRODUCTION Gavin Jones, Hsiu-hua Shen say the factors generally cited as contributing to the rising incidence of international marriage in the region: the increased mobility of population, particularly with respect to tourism, business travel, short-term employment and international study; and marriage market issues in a number of countries of the region, leading to deliberate and targeted search for spouses in other countries. It also reviews the types of international marriages in the region, including the national, ethnic and social characteristics of spouses in such marriages. Finally, it discusses the issues and problems covered and not (or inadequately) covered in the literature of international marriage in East and Southeast Asia in relation to the questions of rights and of the boundaries and sovereignty of the state (Jones & Shen, 2008). According to Xavier Nugraha, he said that it is necessary to determine the age restriction in marriage which aims to make women's lives specifically protected in terms of health. In addition it can protect the psychological influence on women because when women are still said to have not reached the age set by the law, the psychological condition of women is not optimal (Nugraha et al., 2019).
