As for applying for permanent residence in Japan, some say that those who have studied abroad and worked for 10 years can apply, some say that a part of the study time will be counted, some say that the study time of science and engineering will be counted, and so on. Which is right? What are the best ways to stay in Japan for a long time besides work visa and family visa? In fact, there is an objective time limit for any kind of visa, unless you marry a Japanese, then you can get a permanent residence visa after three years of marriage, but the condition is that you must be married in the real sense. So, what is a good way to stay in Japan and realize the desire of running at both ends? It is very simple - after becoming a Japanese citizen and finding a Chinese spouse, you can realize your long-cherished dream naturally. Let's take a look at the specific bidding conditions. According to the provisions of the Japanese Nationality Law, there are six basic conditions for applicants to obtain Japanese nationality: 1. Domicile conditions The applicant has had a residence in Japan for more than five consecutive years. This is one of the most basic conditions, that is, the applicant must live in Japan for more than 5 years, do not meet this condition is not eligible to apply. Applicants must apply in Japan. The previous Nationality Law allowed spouses of Japanese nationals to file applications at the local Japanese consulate, but the current Nationality Law has removed this provision. Of course, the applicant must have the legal status to stay. The applicant's temporary departure from Japan or change of residence will not affect the application. The applicant shall be at least 20 years of age and possess the adult capacity stipulated by the laws of the country. However, the age of 20 mentioned here does not include children who apply with adult parents, because at this time, the application of children is based on the premise that their parents apply for permission, and according to the children of Japanese people, they can be exempted from the ability condition of 20 years old or older. The applicant is of good character. This is also a basic condition for obtaining Japanese citizenship. Generally speaking, after accepting the application, the applicant's occupational status, economic activities, social activities, daily life, whether to pay taxes, whether to violate criminal and administrative regulations are investigated. More detailed is that whether there is a driving violation, whether to comply with the garbage classification regulations, etc., are the object of investigation. If you have violated Japanese laws and been sentenced to prison, you can not apply for a certain period of time after being released from prison. Major tax evasion is treated in the same way. The assets and skills of the applicant and his/her spouse are sufficient to sustain his/her livelihood. The main purpose of this article is to prevent people who are likely to become public charges from acquiring Japanese citizenship. Dual nationality Prevention conditions The applicant is stateless, or the applicant renounces his/her original nationality at the time of acquiring Japanese nationality. In other words, when a Chinese person applies for Japanese nationality, he or she has to go to the Chinese Embassy to renounce his or her Chinese nationality after obtaining the approval of the Japanese Justice Minister. This condition is mainly due to the principle of the uniqueness of nationality, a person cannot have two nationalities at the same time. The applicant shall not join or form a group that seeks to destroy Japan by violence or a political party organization that has similar views. This is a natural condition for maintaining the security of the national community, and not only Japan, but also the United States and other countries have the same provisions. The above are the six basic conditions for applying for Japanese citizenship. The specific application procedures should be carried out at the local legal bureau or branch office where the applicant is located, and the application procedures cannot be handled at the legal Bureau where the applicant is not located. The applicant must be himself or his legal agent, which is mainly to clarify that the applicant does have the intention of obtaining Japanese nationality, and those who do not apply for the intention will be declared invalid even if they have obtained Japanese nationality. The age requirement for determining whether the applicant himself has the intention is 15 years old, and persons under the age of 15 must apply through legal representatives, generally their parents are their legal representatives. In Japan, there are consultation departments for applying for nationality relations in various judicial bureaus, and the examination results generally take about six months to one year to come out.
