什么情况下有哪些文件需要办理领事认证
领事馆加签,外交部盖章,大使馆认证代理；3-5天拿正本-；CO,CI,授权书等各类文件认证

回答内容：我国公民要去国外学习、工作、居住，或是在国内办理出国签证时，通常需要使用某些国内公证处出具的涉外公证书，如出生公证、未受刑事处分公证、授权委托书公证、合同公证等等。

When Chinese citizens want to study, work or live abroad, or apply for exit visas in China, they usually need to use the foreign notarial certificates issued by some domestic notarial offices, such as birth notarization, notarial notarization without criminal sanction, notarization of power of attorney, notarization of contract and so on.

这些公证书在送国外使用前可能需要办理领事认证；企业因境外经贸活动需要，常需向贸促会申请原产地证、发票、装箱单等，或向出入境检验检疫机构申请原产地证明、动植物出口检疫证明书等,上述文书在发往国外使用前，可能需办理领事认证。 

These notarial certificates may require consular certification before they are sent abroad for use; Enterprises often need to apply to CCPIT for certificate of origin, invoice, packing list, etc., or apply to entry-exit inspection and quarantine institutions for certificate of origin, animal and plant export quarantine certificate, etc., due to the need of overseas economic and trade activities. Consular certification may be required before the documents are sent abroad for use.

通常公民个人或企业出国办理事务或进行企业活动，外国驻华使领馆或该国的有关部门会向当事人提出文书领事认证要求。如果对方要求您办理领事认证，那么您应当按对方的要求准备相应的文书。
