我准备出国在一家金融公司工作，觉得自己的英语还不够好，在哪儿报班强化一下比较好呢？

Which country will you go? If you are going to some English speaking countries, like United States. I think the best place for you to improve your English is the native places. In America, there are myriad of churches teaching English for free. There, you not only can communicate with native speakers but you can chat with other international people as well.
