Very urgent please advise

[See lion]

Hi, I need some great help. My lawyer also confused and not giving me any suitable answers. I am currently waiting for a date from upper Tribunal for my appeal. I went to my regular two weekly reporting and they gave me a slip. It says it’s from immigration enforcement and has my name and h/o ref no. It looks like a bank check and yellow. They referred it as complementary slip. I have been advised to show it to security and go to a specific room.
It is on different day other than my normal reporting day. The counter guy told me my reporting will resume to normal after the interview. Now I don’t know what it is about and why they want to interview me. If anyone know anything like this please help me. I am already stressed and this gives me high pressure. Thanks in advance.

Are you sure it wasn't referred to as an Immigration Enforcement compliment slip with the details of where you were to report to?

Yes, yes..it says that. I mistakenly wrote complementary. As I told you ,I am loosing sleep over it. Thanks Madam, please advice me if you know the reason for this interview.

No one can tell you what the interview is about. What does your solicitor say?

By the way...I'm not a 'Sir'. The clue is in my avatar.

He is just guessing. Thinking they will ask me about my case and situation now etc. I am worried about if they try to detain me. I was detained once , it was horrific.
