Will immigrants be investigated after committing crimes?

Legal analysis: This question depends on whether our country and the country where the criminals fled have signed or signed an international extradition treaty with the criminals involved. If there is a treaty, then the host country has the obligation to arrest criminals and extradite them to China, otherwise it has no obligation. In addition, it is an international practice not to extradite political prisoners, that is, whether there is a treaty or not. At the same time, according to the provisions of international law, arresting criminals involves the judicial sovereignty of a country, and other countries have no right to send police to other countries to arrest criminals, otherwise it will infringe on the sovereignty of other countries, which will lead to international disputes and even wars.

Legal basis: Extradition Law of People's Republic of China (PRC).

Article 1 This Law is formulated with a view to ensuring the normal extradition, strengthening international cooperation in punishing crimes, protecting the legitimate rights and interests of individuals and organizations, and safeguarding national interests and social order.
