ICITSS acknowledgement submit time period.

I applied to icitss OC and it said that,

Required documents should be E mailed 2 days before starting of batch.

My query, can I EMail it 4 or 5 days before? or how many days before should i Email?

Do i get any confirmation? Currently portal saying "approval awaiting"
