Methods 1: dual nationality was obtained by birth place.
1, first think about whether your country of birth allows you to have a second nationality. If you are born locally, you are eligible for citizenship with unlimited land rights, which is also known as the principle of unconditional nationality and birthplace. Where you were born, you have the right to obtain local citizenship. For example, if you were born in the United States, but you are a British citizen, you have the right to obtain American citizenship on the principle of unconditional nationality and birthplace. Study the immigration laws of your country. Most countries do not grant citizenship to others on the grounds of territorial rights, so it is necessary to study the laws of your country of birth.
In the global 194 countries or regions, 30 countries or regions follow the principle of unconditional nationality birthplace. Among these 30 countries, Canada and the United States (as of 20 10) are the only two developed economies in the world that follow the principle of unconditional nationality birthplace, and most children born in their territories are granted citizenship, including children of illegal residents.
However, children of other heads of state and diplomats born in the United States will not acquire American citizenship because of land rights.
2. Know how to exercise citizenship through unrestricted land rights. If you find that the country of birth (not the country where you enjoy civil rights) gives you civil rights through the principle of territorial rights, you should know how to use this right. It is a citizen's right to apply for a passport. You can apply for a passport at the embassy or consulate where your current nationality is located. They may ask you to submit the original or copy of your birth certificate.
For example, to apply for a Canadian passport, you must submit a Canadian birth certificate. This certificate was issued by the place of birth. Canada follows the principle of unlimited nationality and place of birth, so this can be used as proof of Canadian nationality.
3. Study the laws of the two countries on dual nationality. Understand the domestic laws on dual nationality and learn the laws of other countries (applicant countries) on dual nationality at the same time. If you are naturalized through land rights, do you need to give up your current nationality? This is important because not all countries that follow the principle of unlimited nationality and place of birth allow citizens to have dual nationality. For example, Pakistan implements the policy of unlimited nationality and birthplace (with a few exceptions), but only citizens of some States can have dual citizenship.
In the United States and Canada, for example, both have implemented the policy of unlimited nationality and place of birth, and also recognize dual nationality.
Method 2: Obtain dual nationality through parent-child relationship.
1. Start with the nationality of your parents. Most countries in the world grant citizenship according to blood relationship. According to the principle of descent, one or both parents can acquire citizenship at birth. Therefore, no matter where a child is born, she can obtain the citizenship of her parents, and if she is born in a country that does not implement the policy of unlimited nationality and place of birth, the only way for her to obtain citizenship is through blood relationship. For example, you were born in the United States, but your parents are British citizens, so you are also British citizens.
2. Study the laws of the two countries on dual nationality. Find out whether this country will require you to give up your current nationality if you acquire a second nationality by the principle of descent. If so, you can't be a dual citizen. Both the United States and Britain recognize dual citizenship. Other countries grant citizenship according to the principle of descent, but do not recognize dual citizenship.
For example, Singapore implements the principle of descent nationality, but does not recognize dual nationality.
3. Understand how to exercise citizenship through the principle of descent. Different countries or regions have different application procedures for obtaining citizenship through parent-child relationship. Consult the consulate of the country for relevant information. For example, if you are an American citizen born to British parents and under 18, then your parents must apply for British citizenship on your behalf.

Method 3: Obtain dual nationality through investment.
1. Obtain a second nationality through investment. Many countries will issue residence visas to individuals who are willing to contribute to their own economy, and after a few years, they will be eligible to apply for citizenship with these residence visas. This method is very expensive, because the minimum investment varies from several hundred thousand dollars to several million dollars. For example, the United States needs to invest 6,543,800 US dollars to obtain a conditional permanent residence permit. If you are investing in high unemployment or rural areas, 500,000 US dollars will be enough.
2. Understand how long it takes to obtain citizenship through investment. This method may take a long time, so you'd better know how long it will take before investing. For example, the United States and Belgium will grant citizenship to individuals holding such residence permits in five years. Malta (with a minimum investment of 6,543.8+0,000 euros) can only obtain citizenship after 654.38+0 years.
3. Understand whether there is a requirement for the length of residence. Some countries that issue investment visas also require them to be residents of the country before becoming citizens. However, not all countries have residence requirements. For example, Cyprus has no residence requirements, while the United States does.
4. Understand the local citizenship laws. Not all countries recognize dual citizenship. You may need to give up your current nationality to get the second nationality you invested in. If it is, it cannot be a dual citizen.
Method 4: Obtain dual nationality through marriage.
1. Start with your spouse's nationality. If you marry a foreigner, consider whether your spouse's country will grant you citizenship because of marriage. The process includes the link of being eligible for a residence permit because of marriage, and so on. Other life requirements must be met. If you think you can get a second nationality through marriage, you should know the civil law of your spouse's country. The relevant application procedures and the time required to obtain citizenship vary from country to country or region.
For example, if you marry a British citizen, you must meet certain requirements before you can apply to become a British citizen through marriage. You must be 18 years old or above, sound in mind, good in personality (if you have no serious criminal record), meet certain English proficiency requirements, have some common sense of life, and must stay in the UK indefinitely and meet the residence requirements.
2. Know the consequences of fake marriage. Note: Fake marriage in order to obtain the right of abode and citizenship in the country where the spouse is located will be regarded as fraud, and most countries or regions will regard it as a serious criminal offence. Don't try to get married in order to have dual nationality, which will have serious legal consequences.
3. Understand the legal provisions of the two countries on dual nationality. Not all countries recognize dual nationality, and it is possible that your spouse's country will ask you to give up your current nationality. If so, you can't be a dual citizen.
Method 5: Obtain dual nationality by other means.
1, apply for a work visa. You can also obtain citizenship by applying to work in other countries. Some countries allow individuals with work visas to change their visa status to permanent residence and then become citizens. For example, in Australia, you can apply for various types of work visas. Of course, these visas also have certain requirements. One of them is called a technical independent visa. You can always work in Australia as long as you meet the requirements. If you have lived in Australia for four consecutive years with this visa, you are eligible for Australian citizenship.
2. Apply for the right of abode through the special immigration plan. In many countries, the first step to becoming a citizen is to have the right of residence. Once you become a resident, you can apply for citizenship. Qualification requirements vary from country to country. For example, in the United States, permanent residency can be obtained through multiple immigrant visa programs. The plan is to randomly select immigration applications from countries with low immigration rates and give them immigration qualifications.
See if there is a similar way to obtain the right of abode in the country where you apply.
You can apply for citizenship as long as you have the right of abode and meet all the criteria.
3. Understand the legal provisions of the two countries on dual nationality. It must be remembered that not all countries recognize dual nationality. If you obtained your citizenship through a work visa, visa lottery or other immigration programs, you may have to give up your current nationality. If so, you can't have dual nationality.
Tip: Each method of obtaining citizenship requires filling out a series of forms related to the citizenship or residence type you are applying for. These forms and processes vary from country to country. The website of the consulate will provide relevant information and guidance.
It is possible that your country recognizes dual citizenship, but it does not encourage it. Legally speaking, the United States recognizes dual citizenship, but this may lead to some problems. For example, when the laws of the United States conflict with those of your country, it is difficult for the United States government to provide consular protection. So the United States regards dual citizenship as a policy issue. Your country or region usually prefers you to stay. If this country or region does not have stable political relations with the United States, some conflicts may occur.
Remember, citizens with dual nationality must abide by the laws of both countries. Because both countries can interfere with your civil rights, especially your present country.
