你相信帮助你申请签证的人吗？根据我们的经验，许多中介公司会利用申请人被拒签这一点让申请人付更多的费用 。请注意：要对申请材料负责任的是你自己，而不是中介公司。

Do you trust the person who helped you with your visa? It is in many of their best interests’ that you are refused so you pay them more money to apply again. You are responsible for what is on your application, not the visa broker.
