ReApplying for Step 1, how long it takes for the permit

Hi,

I hav my exam in the end of this month, which for some reasons i will not be able to take it ... Now since i wish to take the exam by about 10th November, my question is ... how many days after cancellation of the exam in the extended period and reapplying again, will i b able to get the new permit, so tht i can take the exam ???

My Permit for this slot is over and i need to reapply ... and My Credentials are verified ... so tht means it should not take more than a week, i guess to get the new permit ...

Does anyone has a similar experience ??? or can anyone advise regarding the same ???
