Since the immigration process seemed to be quite thorough, it made sense that Lex would be questioned in detail about his purpose. Considering that he learnt that the invitation he had was from a supposed prison, he had already prepared himself to face some difficulty. But the issue was, Lex wasn't really facing any problems at all. In fact, even during the questioning process everyone was quite civil.
