Yes, in most cases, someone else can submit a China visa application on your behalf, but this convenience is governed by strict rules. Whether you use a family member, friend, or a professional agent, the success of a third-party submission hinges on one critical document: a signed letter of authorization. The Chinese Visa Application Service Center (CVASC) needs undeniable proof that you have explicitly permitted another individual to handle your sensitive documents. Without this, your representative will be turned away at the counter, causing significant delays to your travel plans.
