Because I went to the Embassy myself and ask them some information about my case.

They checked it on computer and told me my case is almost at the end. And I should
have the second interview in July. I was so surprised and can't help asking them why I
should have the second interview. Because I never heard it before and have no any preparation
in mind. They became impatient and told me sometimes they need the second interview to validate
it. They also told me they will send me a letter about it.
