Okay I just called the board. According to them, you need one year public or 1 year nonpublic work perform under CPA supervision and includes intenstive auditing or accounting work.

That's a great news. If this is ture than I am done.

Although, I am not done, This is good news for me as well ( I do have more than 4 years of Non Public experience, I may not get all the letters)

Thanks Mansi and rebesteves, for the information.
