Is there the simplest and most convenient way to change nationality?

Changing nationality is very troublesome. First of all, you have to obtain permanent residency, that is, immigration rights.

Immigrants mainly include investment immigrants and skilled immigrants. At present, Canada and Australia are the two countries with the largest types of open immigrants.

Canada and Australia can only apply for naturalization after holding immigrant visas for five years, and the naturalization review is very strict.

Singapore can apply for naturalization two years after obtaining an immigrant visa.

Foreign nationals must apply for visas to China, and China will open visa-free entry for overseas Chinese, but it has not yet.

Singaporean citizens can get 14 days visa-free for China.

Citizens of other countries must apply for a Chinese visa. There is a time limit, so I can't stay in China all the time.

Australia and Canada can be exempted from signing in most countries, Singapore can be exempted from signing in other countries in Southeast Asia, and Japanese and Korean passports can be exempted from signing in some countries.

Immigrants need conditions other than marriage. Either you have money or you have talent.

Being rich means being rich, or being an investment immigrant. Hong Kong investment immigrants need HK$ 6 million. Australian investment immigrants need 500,000 Australian dollars.

Talent is skill. The countries that open skilled migration are mainly Canada and Australia, while other countries have more restrictions. Immigrate to Canada or Australia through skills, or study there. If qualified, you can immigrate after graduation. Or you are an excellent talent. If you can get a job guarantee from a company in Australia or Canada, you must have a major that is in short supply there.

No country can directly acquire nationality. And immigration is not that simple.

In other words, you must be rich or talented, and it is not so easy to find someone to get married there.
