My sister lived in Britain for 10 years and obtained a British passport for more than 8 years. I am his own brother. Can I apply for immigration?

If you are a minor and have no other guardians or dependents in China, you may still have a chance to apply. Otherwise, it is unlikely.

In fact, what Jia Mian said on the second floor is not irrelevant. I met a lot of people from Fujian and Zhejiang in Germany and France who did the same. A woman from Qingtian, Zhejiang, China, married her brother in France in order to help him acquire French identity. Of course, she and her brother both live with real partners and even have children, but legally the brother and sister are husband and wife.

There is also a person from Yueqing, Fujian who has returned to China and married his sister, so she can come to Germany.

It seems that domestic management, especially those small places in the south, is not so strict and there are many loopholes.
