(急!)用英语写一篇书面表达为:假设你是李华,你的好友王宁想去美国留学,但是他自己犹豫不决,请你给他提意见

Hi Ning,
As I suppose, it is a good opportunity for you to study in the United States. First of all, there are more advanced colleges and universities which would definitely bring you good chance to equip yourself with much knowledge and skills that are essential to live a good life in the States. Plus, experiencing culture in a different country is pretty cool! The United States is a brilliant cross-cultural country in which you can experience much.
I hope you can have great experience abroad.
Sincerely,
Hua Li
