邀请父母，朋友来美国要哪些文件？英语不好的父母来美国有哪些需要提前准备的英文文件？Vivian根据自己以前邀请父母，家人以及朋友时所写的文书，为大家整理了办理签证，入海关时需要出示的几分文件的模板，供大家参考！（文中的模板均为Vivian自己编写，供大家参考，Vivian也准备了文字版本，方便大家如有需要复制黏贴适用，也请大家根据自己的实际情况填写内容）
总的来说，邀请家人来美国，邀请人可以为被邀请人准备的文件有以下几种：
邀请函
美国签证行程单
入关信件
美国签证邀请函
邀请函没有固定的邀请函格式，主要是表明邀请人的信息，被邀请人的信息，被邀请人赴美目的，与邀请人的关系等等即可。请大家务必注意，邀请函一定要确保信息的准确和真实，这也会直接影响被邀请人签证的通过率。

办理美国签证，尤其是B1/B2旅游签证，有完整的美国签证行程单是非常有帮助的，并且这份行程单在签证时也可以使用。

VIvian的小总结
不管是美国签证邀请函，还是签证行程单或者入关信，其实都没有一个固定的模板，写的时候只要保证信息真实正确就可以啦！
