你可以写一封信给王先生说明我们的具体情况吗?这是唯一的办法,用英文怎么写,用英语怎么说?

Could you write to Mr Wang and explain our specific conditions?This is the only way/solution.Please!
如果你满意我的答案,这是对我们答题者劳动的尊重,多谢!谢谢你团长，我现在想说：“之前我和房先生一同前往意大利签证处，并告诉签证处我们是去演出，申请表是我的同事填写的，她并没有勾选旅游，我昨天才知道因为没有合同及警察局的认证所以签证官根据我们提供的材料，认定是一个旅游签证，而在此之前没有任何一个人告诉我们合同和警署认证的事情，所以，很遗憾，现在只能按照您的提议去做”谢谢，能帮写一下这段话吗，我加分的，谢谢你Beforetime I went to the Italy visa office with Mr Fang, and told them we would go to Italy to give a performance. It was my colleague who filled in the application form, and she didn't check the "tour" item. Not until yesterday did I know that the visa official identified it as a tourist visa according to the documents we had offered. However, we had never been informed that we needed the contract and the authentication from the local police station before. What a pity! Now we'll have to do as you advised.
