Can I apply for an extension of my American immigrant visa?

Legal analysis: American immigrant visa can be extended. All B visas in the United States can be extended. Within 48 months after the visa expires, the same type of visa can be renewed without face-to-face signing, and the information can be transmitted on its behalf. If it is more than 48 months, you need to make an appointment for a face-to-face interview. Consistent with the reprocessing process. In the past, overstaying or staying in the United States for too long may also require a face-to-face visa.

Legal basis: Regulations of the People's Republic of China on Passports and Visas Article 1 Passports of the People's Republic of China are identity documents issued to China citizens for entry and exit. Passports are divided into diplomatic passports, official passports and ordinary passports (ordinary passports are divided into ordinary passports for business and ordinary passports for personal reasons). The passport issuing authority may also issue other documents instead of passports when necessary.
