我明白了，也就是说我首先需要的最基本的文件就是一封邀请函，那么我会给这次会议的主办方发一封电子邮件，要求他们给我发一封邀请函。

OK. I see. That means the invitation letter is the basic document I need to have. Then I will email the organizer of this conference to provide me with an invitation letter.

如果需要，法院也许要求感兴趣的人邀请专家出现在法院面前。

If necessary, the court may require an interested party to invite experts to appear before court.
