In the face of impacts coming along with domestic population aging and low birthrate, “birth” is not the only solution any longer. In virtue of immigration, we can supplement workforce while postponing the population aging. Furthermore, the “chain immigration” is commonly found in international society. Both sham marriage and real marriage are important factors of transnational matrimony for influencing social development.
By centering on the naturalization of countrymen without Taiwan nationality or stateless persons who get married with Taiwanese, the government shall take the following factors as references for formulating guidance policy regarding population and transnational marriage: the divorce rate after naturalization, time series of marriage and divorce after naturalization, the number of people who get married with their original fellowmen (foreigners or natives) after divorce and so on.
We studied the marriage status of foreign spouses after naturalization during the period from 2008 to 2016 in this paper. According to the statistical result, the number of foreign spouses from Vietnam accounted for a maximum ratio of 78%. After naturalization, about one in four persons got divorced. This ratio was obviously higher than the roughly estimated divorce rate of countrymen (14%, the ratio of the number of divorced people against the total amount of the number of married persons plus that of divorced people). Based on the data of time series, the divorce rate within one year after naturalization reduced from 1.76% in 2008 to 1.59% in 2016, and also reduced from 8.08% in 2008 to 3.82% in 2015 within 1-2 years.

It revealed that the intensive guidance policy of foreign spouses marriage in recent years had gradually give play to functions and the divorce rate had tended to decline. Besides, people after naturalization can obtain their identification cards after residing for one year at the soonest. Among Divorced people, those who stayed for “over 1 year and less than 2 years” accounted for about 32%, and the divorce rate of people with Cambodian nationality accounted for the highest proportion of 33%. As to people who get divorced after naturalization and people who get married with their original fellowmen (or foreigners) after divorce, Vietnamese accounted for the highest proportion. Furthermore, with respect to female foreign spouses after naturalization, those who get married with foreigners within 3 years after divorce accounted for nearly 70%. It showed that after naturalization, the situation that foreign spouses getting married with foreigners after divorce still existed every now and then in short term.
The aforesaid cases can all serve as reference for foreign spouses’ application of naturalization, as well as the life guidance policy concerning them. For the guidance policy of foreign spouses marriage had taken effect, the paper finally suggested that the immigration unit shall persistently drive the life guidance policy of foreign spouses and occasionally enhance inspections during the residence period of foreign spouses. Moreover, the household registration unit shall continuously reinforce the investigation of real parts of marriages in
the naturalization cases so as to prevent the phenomenon of sham marriage."
If the authorities have any doubts about my marriages, I’m fine with any investigation. I’m just worried what if they are not honest and come up with some unjustified reasons to deport me.
