尊敬的签证官先生您好：
Dear Respected Officer:
我此行一人(需要说明几个人),经澳大利亚的悉尼前往瓦努阿图的维拉港(需要注明什么目的,是商业目的吗?) .
We,as a team are going to PORT VILA,THE REPUBLIC OF VANUATU for business purpose via Sydney.
中国公民去瓦努阿图有免签证待遇.
As we noticed that it is not necessary for Chinese citizens to apply a secondary visa.
特做此书面证明.
We hereby certify this in written.
