    I am sure

    Hello,

    I would like to know if there are specific grammmar rules when we use the expression "I am sure"/ "I am nor sure" at the beginning of a sentence.
    Do we have to use a certain verb tense? Or, on the contrary, it only depends on what the speaker wants to say.

    E.g.- I am sure I am going to Paris this summer.
    I am sure I will go to Paris this summer.
    I am nor sure if I will go to Paris this summer.
    I am nor sure if I am going to Paris this summer.
    I am nor sure if you should do what you are doing.
    etc.

    Thank you for your help.

    Re: I am sure

    All of your sentences are fine (if you change 'nor' to 'not'), as are:

    I am sure I was in Paris in 1982.
    I am sure I have been here before.
    I am sure I hadn't seen him before that day.
    I am not sure I would have accepted the job if he had offered it
    .
    etc

    And I am sure I had a reason for coming upstairs, but I can't... oh yes, that was it.
