签证申请被拒有多种原因，拒签理由一般也不告知申请人。一次被拒签并不意味着永久被拒签，申请人按使领馆要求在一定期限后可再次申请。如按使领馆要求提供充足可信的申请材料（包括有良好的履历和该国签证申请记录），仍有希望顺利获签。
There are many reasons for denying visa applications, and applicants are generally not informed. A denial of a visa does not mean a permanent denial of a visa. Applicants can apply again after a certain period of time as required by embassies. If the embassies and consulates require to provide sufficient and reliable application materials (including good history and visa application records of the country), there is still hope to be successfully signed.
