Is there any time limit for economic investigation from filing to closing? There is no time limit from the time of economic investigation and case filing to the time of case closing, because the time required varies with the complexity of security. Generally, the case should be completed within two months from the filing to the conclusion of the investigation; If the case is complicated and cannot be concluded at the expiration of the time limit, it may be extended for one month with the approval of the People's Procuratorate at the next higher level; This period can be extended for another two months if:
 1、 Major and complicated cases in remote areas with very inconvenient transportation;
 2、 Major criminal group cases;
 3、 Major and complex cases of wandering crime;
 4、 Major and complex cases involving a wide range of crimes and difficult to obtain evidence.
 If the criminal suspect may be sentenced to more than 10 years of fixed-term imprisonment, and the investigation cannot be completed within the above-mentioned period, it may be extended for another two months upon approval or decision of the People's Procuratorate of the province, autonomous region, or municipality directly under the Central Government.
 According to Article 156 of the Criminal Procedure Law, the period of investigation and detention of a criminal suspect after arrest shall not exceed two months. If the case is complicated and cannot be concluded at the expiration of the time limit, it may be extended for one month with the approval of the People's Procuratorate at the next higher level. The above is an analysis and answer to the question of whether there is a time limit for economic investigation from filing to closing. I hope it can help you.
