applying citizen application

Hi All: I have one small tricky question, my retention application is in process, wondering can I apply for Citizen application as my citizen application time is over due and retention application is still in process from last 13 months and now they send me Temp stamp 4 for next 4 months..

I saw the INIS site and I didn't find the answer, all what I saw if you are in state for number of days, with reckonable stamp you are eligible to apply citizen application..

would really appreciate your thoughts..

Thanks,
