#Urgent

3-4 days

And where do i get it ?

Do they mail it or have to download from their site ?

2 days doc. It will be made available for download when you login

After online payment and uploading photo and signature, do we have to do anything else or just wait for them to upload ?

They have approved the docs and i am just waiting.

Do we have to get anything verified or what ?
